Emulators

This page contains RetroArch and Stand Alone emulator options for systems that will run on the RP2.

It is not recommended to update the pre-installed emulators, as the Retroid developers seem to have chosen these builds because they run well on the device. There are a few instances where this rule does not apply, and are noted below.

The RP2 comes pre-loaded with RetroArch 1.8.4 & 1.5.0 with the following cores:

RetroArch 1.8.4

RetroArch 1.5.0

• Game Boy Advance (gpSP) This is installed separately because RA 1.5.0 has the best performance for gpSP/GBA

The RP2 Comes with these Stand Alone Emulators Pre-installed:

• Flycast (You will need to configure Reicast and configure the Bios. See DC notes at the bottom of this page)

• MAME4droid(0.139u1) (You will need a .139 MAME Romset)

• Mupen64Plus FZ (Use recommended rendering profile per game for optimal performance. Here is Mupen's settings & render profiles if you lose them, copy to internal storage.)

• N64oid (C stick does not map)

• NeoDroid - NeoGeo MVS Emulator (Compatible with MAME Roms. Put neogeo.zip bios file in your roms directory “/sdcard/neodroid/roms”)

• PPSSPP (Use the recommended profile settings per game for optimal performance)

• Reicast (The back end for Flycast)

• ScummVM (shows no directories on launch. Fix is to search for a game and place a “/“ in the search box and select “Choose”. This will bring up the directory listing)

This table of stand alone (SA) apps & RetroArch (RA) cores seem to get the best performance out of the device. We have prioritized RA cores over SA apps whenever possible, and only if performance is equivalent or better. We have also prioritized SA Free Apps over SA Paid Apps whenever possible, and again, only if performance is equivalent or better.

Dreamcast Configuration Tips

Configuration for the pre-installed Flycast Stand Alone app is done through the pre-installed Reicast app. Flycast will have better performance than Reicast.

Open reicast and click on the DC bios and format memory card 1. For controller settings, set the ports of all to none, and the port for Android Playstation to A. Click Map, and map the buttons to their appropriate locations - you may not need to map all buttons. Click Done, then Done again. You may now close Reicast.

Launch flycast, which shares a config with reicast, and load and play your game.

If there are issues with the controller, you may need to modify the .cfg file in flycast. To do this, go into the directory path for Flycast and find the folder named mappings. Inside, there should be a file named Android_Playstation3.cfg. Open the file, scroll to the bottom, and erase the line for deadzone value. This should not be needed if Reicast 20.02b or newer is installed, or if you have used the .cfg file.
