===SD Cards===
A great alternative guide can be found at <br>
* [http://wagnerstechtalk.com/retroidp2/ Wagner's RP2 Tips] - Beginner tips and tricks by Wagner's Tech Talk
 
==== Adding your own ROMs to RetroidOS ====
 
If these instructions don't exactly match the way you've set up your own RP2, you'll already know enough to change those steps on your own, so I'll assume that you're doing this with a unit fresh from the factory.
 
# Safely eject your micro SD card from the RP2. If you aren't sure how to do that, just turn the unit off completely (not just standby), then remove the card. The micro SD card slot is on the bottom of the unit, under a rubber flap. After you lift the flap (it's NOT a plug that comes out completely), push the card INTO the slot slightly with your thumbnail. It is held in place by a mechanism kind of like a clicky ballpoint pen. Pushing it in slightly until it makes a soft click will cause a spring to push it out so you can grab it easily. Do not use tweezers or any metal tools, as you will probably damage the slot.
# Connect the micro SD card to a computer with a suitable card reader. If your computer tells you that the card must be formatted before use, DO NOT FORMAT THE CARD. There is (probably) nothing wrong with it, and it contains hard-to-replace files that are required by Retroid. If you see such a message, try using a different card reader, or a different computer.
# On the computer, copy any ROM files you want to transfer into the "/games/download/" folder on the micro SD card. This might also be a good time to make a backup of the files that came on the micro SD card with the RP2, in case something happens to the card later. Once the copy is complete, safely eject the micro SD card from the computer.
# Reinsert the micro SD card into your RP2. Push it into the slot until you hear a soft click; this will be a little further in than flush with the edge of the slot. Don't forget that the micro SD card should be inserted with the face (printed side) down (away from the screen side), and the back (plain black side) up (toward the screen side). If you switched the RP2 off, turn it on again. If it is in Android mode, switch to Retroid mode.
# In the Retroid system, hold the "HOME" button until the system menu appears.
# Move the highlight to "Enter game settings" with the d-pad or left thumbstick, and then press "A" to select it.
# Move the highlight to "External games management" with the d-pad or left thumbstick, and then press "A" to select it.
# Using the controls shown on the right side of the screen, select a game to add to the Retroid's game menu.
# A window will pop up, asking you to choose an emulator for this game. Move the highlight to the appropriate emulator name with the d-pad, and then press "A" to select it. Only the short emulator core names are shown, so if you can't figure out which emulator is the correct/best, you may need to do some research. [[Emulators#Emulation_within_RetroidOS|This list]] may help.
 
Your game should now be available from the Retroid game menu. If you have finished adding games, press "Y" until you get back to the main game menu. Enjoy!
 
NOTE: Some people have commented that game files must not be zipped. These instructions have only been tested with a regular (uncompressed) Super Famicom game. There may be additional issues with using zipped files or multi-file games (e.g. bin/cue disc images). Also, this process will not work without the RetroidOS files present on a normally-formatted (i.e. not Android "internal storage") microSD card, even though RetroidOS will appear to be working normally otherwise.
 
== SD Card Options ==
 
The RP2 comes with a 32 GB microSD card. Do NOT format or erase this card before backing up the files it comes with, as these are the files required for RetroidOS to work. If your card is erased, damaged, or accidentally formatted, you can find the necessary files (but without any games) [https://drive.google.com/file/d/1Li1LR9Lc9-cMIFtM7UXWPB8oDDTPqtAi/view here]. If you want more than 32GB of storage in your RP2, you will need to replace the 32GB card with another card. If you want to use RetroidOS with a new card, you will also need to copy the critical files over to the new card, in exactly the same directory structure. For advice on which microSD card to buy, see [[Accessories]].
 
Whichever micro SD card you use in your RP2, it can be set up either as internal storage or external storage. Depending on your needs, you may wish to have both an external and internal card, or just one or the other. To swap between cards, make sure to turn off your device before removing one card and inserting the other. If you have an internal card and an external card, you will need to boot up the RP2 in one mode or the other with the incorrect card inserted. In this case it is probably best to swap cards while switched off in RetroidOS mode, as this likely offers less chance for damage to critical files.
 
=== Linking your internal apps to External SD card ===
 
There is another option to use your external card as storage for your apps. Advantages to using external card as internal storage is, you can still use your external sd card at card readers; you can move your apps back to internal storage if you want to replace the card; if you don't link system apps from internal storage to external card; you will be safe even if the external card gets corrupted. Also you can continue using RetroidOS with this option if you choose to. Lastly, you won't have any trouble with OTA updates.
 
To be able to do this first you need ROOT. Refer to the rooting section under Firmwares on this wiki. Afterwards, you will need a program as Apps2SD. Download it from Google Playstore. Open it, you will need to use "Partition Tool" from the first main menu. WARNING: This will delete your whole card and you should do a backup before doing that. You will have 3 options at Partition Tool, first one is for Rom storage; make it as FAT32 format, second one is for moving the apps; make it an "ext4" and the third one is for "swap" that is supposed to add more RAM for the system to use. Resize the partitions to your liking and hit "yes".
 
Device will reboot at that point. Open Apps2SD,  click "Link Apps to SD card"; it will ask you to create mount script. Choose ext4 and from below, tick the box to the left of "Advanced". It will say "Success!" on this point and apps will show up. Just choose the app you want to carry to external sd card and click Link from bottom right and it is done.
 
=== Using Your SD Card as External Storage ===
 
If you would prefer to use your micro SD card in card readers and other devices, and don't want to install many Android apps to your RP2, you will probably want to keep the card as external storage. Additionally, if you want to use RetroidOS, you cannot use a card formatted as internal storage; while your RP2 will still appear to boot normally into RetroidOS, you will not be able to access or install any games.
 
To use RetroidOS with a new micro SD card, you will need to copy the files from your original 32GB card over to the new card. These files include encryption keys and support files that will allow RetroidOS to read stored games, to install new games from local files, and to access the Retroid "online store".
 
Some guides recommend using partition management software (e.g. MiniTool, Disk Genius) to make a complete backup of the partition on the included 32GB micro SD card, and then write this backup to your new micro SD card. If you are comfortable working with partitions and drive images, this can work very well. However, it doesn't appear to offer any advantages over simply formatting your new micro SD card to "exFAT" and then copying all the files over normally. Furthermore, if you make a mistake during the partition copying process, it is possible to introduce errors into your micro SD cards which would require more work to repair.
 
== Controller Settings ==
 
The controller is already setup in RetroidOS, and should also already be set up in all emulators in Android. If you are prompted to choose a controller, the RP2's own controls will be listed as "Playstation 3".
 
=== Joystick Mode Toggle ===
 
The "Toolbox" app in Android has a setting labelled "Joystick Mode Toggle". This will change how the RP2's left analog stick appears to all apps within Android. The options are:
*Analog Square mode - Apps will see the left joystick as an analog stick, but it will only register movement in eight directions (up, down, left, right, and diagonals).
*Analog Circle mode - Apps will see the left joystick as an analog stick, and it will register the full range of movement in all directions.
*Retroarch mode - Apps will not see the left joystick at all. Any movement of the left joystick will be copied to the d-pad.
 
=== Setting the correct button order for Android games ===
Android games have swapped button order on Retroid Pocket 2, this is how to fix it.
 
WARNING: This is a dangerous process and if you do something wrong, you might need an external keyboard to fix your device's input. Also requires ROOT. Refer to that section to root Retroid Pocket 2.
 
Download an app called Gamepad Tester, (not Gamepad Test preinstalled) switch to gamepad mode. Click some buttons and take note of Product (mine is Vendor_2020_Product_0111)
 
Now open MIX app. Move to root folder, system, usr folder and keylayout folder. There you should see the product name with .kl extension. First take a BACKUP of it just in case to a folder you can remember. Open it as text with Code Editor. Then what we will do just swap key 0X130 Button_A to Button_B, B to A, Y to X and X to Y. Now save the file and reboot. Play GTA and other android games with correct button setup afterwards.
 
== Further Configuration ==
 
=== Google Accounts on Android on the RP2 ===
 
The RP2 offers Android 6.0; with this you can link a Google account to the device for use with Google services like the Play Store. If you don't want to link your personal account, you are also free to use your RP2 without any linked accounts, or you can create a new, "dummy" account for the device. You could also use FLOSS/free/libre alternatives to get new apps and install them manually (a.k.a. "sideloading").
 
To do that you can use the [https://f-droid.org F-Droid] app catalogue for managing the FLOSS apps, like Moonlight or Retroarch (adding the [http://fdroid.libretro.com Retroarch repo] first; which normally is a version newer than the one available from the Play Store). You can also use [https://auroraoss.com/app_info.php?app_id=1 Aurora store](also in f-droid) a direct alternative to Play Store, to manage all the apps (like Steam Link).
 
Finally if you have any privacy concerns you can safely disable (in the Toolbox app) the google apps like:
 
* Google Play Store
* Google Play services (also '''GSF''' Google Services Framework)
* Google Contact Sync
* Browser (replace with Firefox/Fennec is recommended)
* Sound Recorder, Music, Video, Pictures
 
The default apps in the RP2 do not interact with the GSF.

Personally I like to have left trigger as screen swap (I have full screen on the RP2 and switch
to the other screen with L2), also map start and select to the correct buttons and menu to
R2. You can then press R2 to bring up the menu when in gamepad mode. Remember as
above when you are skipping between options that needs to be done in mouse mode, when
you are then pressing the button to map that has to be done in controller mode. {or map my

Then launch flycast, it shares the config with reicast and play the games.

{Flycast config fix comment by u/Chainsaurus} : You need to goto the gamepad config file for
flycast and edit the line towards the bottom where it shows the deadzone value and erase
the line. Go into the folder where your directory path is set for flycast. In a folder called
mappings, there should be Android_Playstation3.cfg. Or you can just install Reicast 20.02b
and not have that issue and still have the same performance, in some games Reicast works
better and vice-versa. {Fixed with Reicast 20.02b onwards then?}
{Taki has mapping .cfg file that should fix this?}

Before You Begin[edit]

WARNING!

Do NOT format the included microSD card. This will result in the loss of the RetroidOS closed system and all pre-installed games. If this happens, a copy of the contents (without games) can be found here.

Do NOT update or delete any of the preinstalled apps or RetroArch cores. Many of these are older or modified versions which have been optimized to work on the RP2. If you are coming from a console gaming background, you may be used to all updates being both required and more-or-less improvements. This does not apply to the RP2: the various installed Android apps are not written specifically for the RP2, but for all Android devices. Due to the age of the RP2's hardware, updates may actually reduce functionality, or cause an app to stop working entirely, due to removal of support for legacy hardware/firmware.

Be careful about restoring/formatting Android. If you do this, you will lose pre-installed emulators and possibly some configuration settings. If this happens, you can find a backup image of Android here, and instructions on the process here. If you need to restore Android to its original state, you will need to flash it. This can brick your device if done incorrectly, so please only attempt at your own risk. Please ask for assistance in our Discord Server if needed.

Applying The Screen Protector[edit]

Follow this helpful video guide on how to apply the screen protector.

Booting Up For The First Time[edit]

When you first power your RP2 on after removing it from the box, it will boot into Android 6.0.

Setting Up RetroidOS[edit]

If you want to use your RP2 as a streamlined, plug-and-play, handheld retro game emulator, please click on this link for a step-by-step guide. On the other hand, if you don't mind getting your hands dirty with Android and fiddling with emulator files and settings, read on.

Once your RP2 is powered on and showing the Android home screen, you should be able to connect your device to your Wi-Fi network through your system settings. WEP does not work on the RP2, so use WPA2 encryption.

If your preference is to use the RetroidOS closed system, navigate to the Toolbox application and select "Install Retroid Pocket App". (If you have an RP1, you'll want to download the Retroid App APK file within the built in browser from https://bit.ly/3bZhcQN and install it with Miix. It shows up under the APK Files menu in Miix). Once installed, open the Retroid app and say OK when it asks to reboot to the Retroid Pocket System. To setup WiFi in the RetroidOS system, hold the Home button for two seconds, and select Handheld settings. Open WiFi and click on Connect WiFi Network, and select the network you wish to join. To return to the Android OS, hold down the Home button for two seconds and click on Switch system. Press OK when asked to reboot to Open Source Android System.

Adding your own ROMs to RetroidOS[edit]

If these instructions don't exactly match the way you've set up your own RP2, you'll already know enough to change those steps on your own, so I'll assume that you're doing this with a unit fresh from the factory.

  1. Safely eject your micro SD card from the RP2. If you aren't sure how to do that, just turn the unit off completely (not just standby), then remove the card. The micro SD card slot is on the bottom of the unit, under a rubber flap. After you lift the flap (it's NOT a plug that comes out completely), push the card INTO the slot slightly with your thumbnail. It is held in place by a mechanism kind of like a clicky ballpoint pen. Pushing it in slightly until it makes a soft click will cause a spring to push it out so you can grab it easily. Do not use tweezers or any metal tools, as you will probably damage the slot.
  2. Connect the micro SD card to a computer with a suitable card reader. If your computer tells you that the card must be formatted before use, DO NOT FORMAT THE CARD. There is (probably) nothing wrong with it, and it contains hard-to-replace files that are required by Retroid. If you see such a message, try using a different card reader, or a different computer.
  3. On the computer, copy any ROM files you want to transfer into the "/games/download/" folder on the micro SD card. This might also be a good time to make a backup of the files that came on the micro SD card with the RP2, in case something happens to the card later. Once the copy is complete, safely eject the micro SD card from the computer.
  4. Reinsert the micro SD card into your RP2. Push it into the slot until you hear a soft click; this will be a little further in than flush with the edge of the slot. Don't forget that the micro SD card should be inserted with the face (printed side) down (away from the screen side), and the back (plain black side) up (toward the screen side). If you switched the RP2 off, turn it on again. If it is in Android mode, switch to Retroid mode.
  5. In the Retroid system, hold the "HOME" button until the system menu appears.
  6. Move the highlight to "Enter game settings" with the d-pad or left thumbstick, and then press "A" to select it.
  7. Move the highlight to "External games management" with the d-pad or left thumbstick, and then press "A" to select it.
  8. Using the controls shown on the right side of the screen, select a game to add to the Retroid's game menu.
  9. A window will pop up, asking you to choose an emulator for this game. Move the highlight to the appropriate emulator name with the d-pad, and then press "A" to select it. Only the short emulator core names are shown, so if you can't figure out which emulator is the correct/best, you may need to do some research. This list may help.

Your game should now be available from the Retroid game menu. If you have finished adding games, press "Y" until you get back to the main game menu. Enjoy!

NOTE: Some people have commented that game files must not be zipped. These instructions have only been tested with a regular (uncompressed) Super Famicom game. There may be additional issues with using zipped files or multi-file games (e.g. bin/cue disc images). Also, this process will not work without the RetroidOS files present on a normally-formatted (i.e. not Android "internal storage") microSD card, even though RetroidOS will appear to be working normally otherwise.

SD Card Options[edit]

The RP2 comes with a 32 GB microSD card. Do NOT format or erase this card before backing up the files it comes with, as these are the files required for RetroidOS to work. If your card is erased, damaged, or accidentally formatted, you can find the necessary files (but without any games) here. If you want more than 32GB of storage in your RP2, you will need to replace the 32GB card with another card. If you want to use RetroidOS with a new card, you will also need to copy the critical files over to the new card, in exactly the same directory structure. For advice on which microSD card to buy, see Accessories.

Whichever micro SD card you use in your RP2, it can be set up either as internal storage or external storage. Depending on your needs, you may wish to have both an external and internal card, or just one or the other. To swap between cards, make sure to turn off your device before removing one card and inserting the other. If you have an internal card and an external card, you will need to boot up the RP2 in one mode or the other with the incorrect card inserted. In this case it is probably best to swap cards while switched off in RetroidOS mode, as this likely offers less chance for damage to critical files.

Linking your internal apps to External SD card[edit]

There is another option to use your external card as storage for your apps. Advantages to using external card as internal storage is, you can still use your external sd card at card readers; you can move your apps back to internal storage if you want to replace the card; if you don't link system apps from internal storage to external card; you will be safe even if the external card gets corrupted. Also you can continue using RetroidOS with this option if you choose to. Lastly, you won't have any trouble with OTA updates.

To be able to do this first you need ROOT. Refer to the rooting section under Firmwares on this wiki. Afterwards, you will need a program as Apps2SD. Download it from Google Playstore. Open it, you will need to use "Partition Tool" from the first main menu. WARNING: This will delete your whole card and you should do a backup before doing that. You will have 3 options at Partition Tool, first one is for Rom storage; make it as FAT32 format, second one is for moving the apps; make it an "ext4" and the third one is for "swap" that is supposed to add more RAM for the system to use. Resize the partitions to your liking and hit "yes".

Device will reboot at that point. Open Apps2SD, click "Link Apps to SD card"; it will ask you to create mount script. Choose ext4 and from below, tick the box to the left of "Advanced". It will say "Success!" on this point and apps will show up. Just choose the app you want to carry to external sd card and click Link from bottom right and it is done.

Using Your SD Card as External Storage[edit]

If you would prefer to use your micro SD card in card readers and other devices, and don't want to install many Android apps to your RP2, you will probably want to keep the card as external storage. Additionally, if you want to use RetroidOS, you cannot use a card formatted as internal storage; while your RP2 will still appear to boot normally into RetroidOS, you will not be able to access or install any games.

To use RetroidOS with a new micro SD card, you will need to copy the files from your original 32GB card over to the new card. These files include encryption keys and support files that will allow RetroidOS to read stored games, to install new games from local files, and to access the Retroid "online store".

Some guides recommend using partition management software (e.g. MiniTool, Disk Genius) to make a complete backup of the partition on the included 32GB micro SD card, and then write this backup to your new micro SD card. If you are comfortable working with partitions and drive images, this can work very well. However, it doesn't appear to offer any advantages over simply formatting your new micro SD card to "exFAT" and then copying all the files over normally. Furthermore, if you make a mistake during the partition copying process, it is possible to introduce errors into your micro SD cards which would require more work to repair.

Controller Settings[edit]

The controller is already setup in RetroidOS, and should also already be set up in all emulators in Android. If you are prompted to choose a controller, the RP2's own controls will be listed as "Playstation 3".

Joystick Mode Toggle[edit]

The "Toolbox" app in Android has a setting labelled "Joystick Mode Toggle". This will change how the RP2's left analog stick appears to all apps within Android. The options are:

  • Analog Square mode - Apps will see the left joystick as an analog stick, but it will only register movement in eight directions (up, down, left, right, and diagonals).
  • Analog Circle mode - Apps will see the left joystick as an analog stick, and it will register the full range of movement in all directions.
  • Retroarch mode - Apps will not see the left joystick at all. Any movement of the left joystick will be copied to the d-pad.

Setting the correct button order for Android games[edit]

Android games have swapped button order on Retroid Pocket 2, this is how to fix it.

WARNING: This is a dangerous process and if you do something wrong, you might need an external keyboard to fix your device's input. Also requires ROOT. Refer to that section to root Retroid Pocket 2.

Download an app called Gamepad Tester, (not Gamepad Test preinstalled) switch to gamepad mode. Click some buttons and take note of Product (mine is Vendor_2020_Product_0111)

Now open MIX app. Move to root folder, system, usr folder and keylayout folder. There you should see the product name with .kl extension. First take a BACKUP of it just in case to a folder you can remember. Open it as text with Code Editor. Then what we will do just swap key 0X130 Button_A to Button_B, B to A, Y to X and X to Y. Now save the file and reboot. Play GTA and other android games with correct button setup afterwards.

Further Configuration[edit]

Google Accounts on Android on the RP2[edit]

The RP2 offers Android 6.0; with this you can link a Google account to the device for use with Google services like the Play Store. If you don't want to link your personal account, you are also free to use your RP2 without any linked accounts, or you can create a new, "dummy" account for the device. You could also use FLOSS/free/libre alternatives to get new apps and install them manually (a.k.a. "sideloading").

To do that you can use the F-Droid app catalogue for managing the FLOSS apps, like Moonlight or Retroarch (adding the Retroarch repo first; which normally is a version newer than the one available from the Play Store). You can also use Aurora store(also in f-droid) a direct alternative to Play Store, to manage all the apps (like Steam Link).

Finally if you have any privacy concerns you can safely disable (in the Toolbox app) the google apps like:

  • Google Play Store
  • Google Play services (also GSF Google Services Framework)
  • Google Contact Sync
  • Browser (replace with Firefox/Fennec is recommended)
  • Sound Recorder, Music, Video, Pictures

The default apps in the RP2 do not interact with the GSF.
