Frontends & Launchers

Frontend/Launcher	Notes
Pegasus	Free. Fast. Immensely and overwhelmingly theme-able (can be skinned to look and behave exactly like any other frontend, given the time and effort). Open-source and actively in development. An absolute pain to configure, and lacks built-in scraping support. Actively being developed (an official Retroid Handhelds launcher is currently being developed with this frontend). Here's a very helpful guide to help you set it up.
Dig	Free. Slow. Theme-able. Super easy to configure, and does have built-in scraping. Development has been abandoned and the app is closed-source. Consequently, this will never be able to launch certain emulators like Flycast and the GBA build of Retroarch included on RP2.
RESET	$5. Fast. Not theme-able (yet). Slick and easier than both Pegasus and Dig to configure. Built-in scraping. Actively being developed. Being customized for the RP2.
RetroX	$12/year. Fast. Theme-able. The easiest out of all of these to configure, by far. Uses built-in emulator cores, giving you handy universal shortcuts in all of your games. Some systems might be faster in RetroX than on the RP2s pre-installed emulators, while some might be slower. Emulation is less customizable than with other emulators. The subscription covers cloud saves, letting you stay synced across any device you use RetroX on, but its worth noting that internet access is required to open your games. Actively being developed and offers a 5 day free trial.
ClassicBoy	$4. ClassicBoy is an all-in-one emulator that uses RetroArch cores. It has cores for PlayStation, GB, GBC, GBA, Nintendo 64, NES, SEGA, and NeoGeo. Contains standard features like audio settings, and save states. The developer hasn’t updated the app since 2014. It gives you free access to basic functions. Paying the upgrade fee is needed for it to be objectively usable.

Pegasus Frontend

A full guide can be found here.

Installation

- First you need to allow non trusted APK installs. Open Settings, Security and mark "Unknown sources"

- Download the app in https://pegasus-frontend.org/#downloads and install it in your RP2

Configuration

Pegasus needs to have a file called metadata.pegasus.txt per system to specify which emulator you want to use, this can be a bit tedious but we've got you covered!

You can download config files for the RP2 emulators here: https://github.com/dragoonDorise/pegasus-rp2-metadata/

All the configs are done using the best emulators as described in this wiki, for DS you should install DraStic, all other systems are emulated with the stock emulators.

FYI: We're still working out the kinks to get N64 configured.

Again, please reference the full guide for a more complete tutorial on Pegasus with the RP2.

Themes

You can use several themes, you would need to create a folder in your SD Card called "pegasus_frontend/themes" and put the theme files in a folder for each theme you want to use.

Here are a couple of Pegasus Themes adapted for the Retroid Pocket's Screen:

[SwitchOS RP2 Edition](https://github.com/dragoonDorise/switchOS)

[gameOS RP2 Edition](https://github.com/dragoonDorise/gameOS)

DIG Frontend

Themes

Copy your desired DIG theme zip file to your device. Do not unzip it as DIG will install themes in zip format.

Themes are installed and selected from within the DIG app in Options tab by clicking on Themes.

- Select "Install theme" and browse the zip file.

- Once installed select the theme from the dropdown menu by clicking "Select theme".
