RetroArch is a multi-system emulator that supports pretty much every video game system. Atari Lynx, Neo Geo Pocket Color, WonderSwan, Game Boy Color, Game Boy Advance, NES, SNES, Virtual Boy, PC Engine/TurboGrafx-CD, PC-FX, Game Gear, Genesis/Mega Drive, Sega CD/Mega CD, Sega Master System, PlayStation 1, Saturn, PSP, and more! Mostly the 16 bit era systems and earlier, but it will do Dreamcast, Neo Geo etc. It's front end for cores ( emulators ) and works really well. Check out their website for all the info. ROMS are not provided but if you're into emulation you likely have a few ready to go. Popular Neo Geo CD emulators include Neo-RAGEx v0.2d for DOS, Neo-RAGEx Windows 9x Upgrade, Neo-RAGEx Windows XP Upgrade. View all Neo Geo emulators. Filter by letter.

Emulation within RetroidOS[edit]

RetroidOS supports the following systems, with the listed emulator cores:

There are no changeable settings for emulators within RetroidOS, and currently there is no way to add new emulation cores.

Emulation within Android[edit]

This section contains free RetroArch and stand alone emulator options. The one paid app that many recommended is DraStic for Nintendo DS emulation.

It is generally 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.

The Retroid Pocket 2 comes pre-installed with two versions of RetroArch (1.8.4 & 1.5.0) and the listed emulator cores.

N64 Core Tips[edit]

You can use N64 in your RP2 with RetroArch (so you can use RetroAchievements, for instance). Not every game runs perfect, and many need further tweaking, but overall you should be pleasantly surprised.

This only works with Mupen64Next or NextGLES2 (GLES3 and Parallel simply crash).

Paste the contents of Mupen64Plus-Next.opt to:

• <internal storage>/Android/data/com.retroarch/files/retroarch-core-option.cfg

Or paste the full OPT file here:

• <internal storage>/retroarch/configs/Mupen64Plus-Next/

Please note:

• Use only glide64 for video (angrylion is slow, parallel simply fails).

• All mupen cores share the same configs.

Stand Alone Apps[edit]

The RP2 Comes pre-installed with the following stand alone apps:

• Flycast - You will need to configure Reicast and configure the Bios. See DC Configuration Tips at the bottom of this page (Flycast is not included on beta batch units).

• 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 - Right joystick will 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 (beta units only have Reicast installed).

• 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.

Best Performing Emulators[edit]

This table of stand alone apps & RetroArch cores seem to get the best performance out of the device. We have prioritized cores over apps whenever possible, and only if performance is equivalent or better. We have also prioritized free apps over paid apps whenever possible, and again, only if performance is equivalent or better.

All Emulation Options within Android[edit]

Click the title of a column to sort the table by the contents of that column.

The performance ratings are:

• A: Plays almost all of the system's games at full speed (or better, for example increased resolution) with few to no glitches.
• B: Plays many of the system's games at full speed, or with minor glitches.
• C: Plays some of the system's games at full speed, or with some glitches.
• D: Technically plays some of the system's games, but often not at full speed, or with major glitches.
• E: Does not run any of the system's games in a playable state.

The cost ratings are:

• Free: Completely free.
• Donation: Completely free, but a voluntary donation is requested.
• Trial: A free version is available, but limited in some way, to encourage users to buy a full/pro version.
• Paid: No free or trial version; only available as a paid app.

Dreamcast Configuration Tips[edit]

This only applies to beta batch units (Pink, Blue, Orange). Later units do not include Reicast, and include Flycast pre-installed by itself.

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

Retroarch Wii Neo Geo Roms

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.
