Gameboy + Color Standard and RetroAchievement use: Gambatte Core. Now there is a new core called Sameboy and according to the website its extremely accurate so u can try that out if getting achievements aren't ur thing. I don't use any of the others. Try moving your retroarch.cfg to another location temporarily and see if that fixes it. If so, you have a bad option somewhere. If not, the issue is probably external. If it's only affecting the single core, you could try a different GBC core and see if the problem is there, as well.

RetroArch is a frontend for emulators, game engines and media players. It enables you to run classic games on a wide range of computers and consoles through its slick graphical interface. Settings are also unified so configuration is done once and for all. In addition to this, you are able to run original game discs (CDs) from RetroArch.

Emulation within Retroid OS[edit]

There are no changeable settings for emulators within RetroidOS, and currently there is no way to add new emulation cores. Switch to the Android OS for custom options.

RetroidOS supports the following systems out of the box, with the listed emulator cores for Retroarch:

System	Emulator Core
Arcade	Final Burn Alpha (2.97.08, 2.97.42, 42_ORI, 42_HOME) MAME (0.37, 0.78, 0.106, 0.139, 139_RA)
NES/Famicom	FCEmu
Master System	Genesis Plus
GameBoy/GameBoy Color	TGB Dual
PC Engine	Beetle PCE
WonderSwan/WonderSwan Color	Beetle Cygne
Mega Drive/Genesis/CD/32X	Genesis Plus
SNES/Super Famicom	SNES9X
GameBoy Advance	gpSP
PlayStation	PCSX (labelled as PSCX)
Nintendo 64	Mupen64 Plus
PlayStation Portable	PPSSPP
Dreamcast	Reicast

Emulation within Android OS[edit]

The Android OS on the RP2 comes pre-installed with standalone Emulator apps and RetroArch (1.8.4), a single application with the ability to emulate many systems cores.

Retroarch Gameboy Color Core

Also included is a single RetroArch (1.5.0) app, exclusively for the best performing GBA (gpSP) Core.

It is generally not recommended to update emulators, as the Retroid developers chose these builds because they run well on the device. This can be done however if you choose to, as emulators and RetroArch cores get improvements all the time.

Emulation is generally prioritised as a RetroArch core first, then a stand alone Emulator second. RetroArch offers internal options across multiple systems, including Online Leaderboards, image filters, and save file paths to allow you to save to a Google Drive or Dropbox for cross-console play.

For help setting up and using RetroArch on the RP2, see A Brief Guide to Retroarch.

The only emulator that does not come standard is DraStic (which is recommended) for Nintendo DS emulation; it can be purchased from the Google Play Store.

Listed below is a table of standalone emulators & RetroArch Cores for best performance. Systems listed as A are Recommended (usually installed as default) and optimal for the Retroid Pocket 2, although harder to emulate systems may still show issues.

The performance ratings are:

A: Recommended. Plays with few to no glitches.
B: Playable. Plays with minor glitches.
C: OK. Plays some games at full speed, others with issues.
D: Unplayable. Technically runs games, but with major issues.
E: Does not run.
