Improving RG505M’s Software Using GammaOS
Information
GammaOS is based on LineageOS 19.1 (Android 12). It provides a debloated and performance optimized experience for users who are looking to get the best out of their Anbernic RG405M and RG505.
Features:
- Based on debloated and clean LineageOS 19.1 build, Android 12 for a smoother experience. GammaOS includes Google Services and Play Store. GammaOS Lite excludes Google apps and services for extra performance headroom.
- Daijisho launcher as front-end, pre-configured with RetroArch for some systems. (Optimized settings for GB,GBC,GBA,NES,SNES,Genesis,PSX) (BIOS files need to be supplied by you).
- Aurora store included.
- Adguard ad blocking included as default (can be disabled via Private DNS settings).
- Magisk/root included. Ignore any warning about additional setup required, this is a false flag. Magisk is working fine.
- 60hz refresh rate fix for display (stock is 61.2hz and can cause frame pacing issues with emulation).
- Oversharpening display fixed.
- Analog stick calibration for more tighter controls.
- CPU, GPU, Memory now using performance governors for extra performance boost.
- Experimental GPU drivers taken from Retroid Pocket 3+.
- L2/R2 fixed for apps and games with issues with those buttons. Change between XBOX and NS button layout by holding L3+L1+R1. Settings saved across reboots.
- Toggle between performance modes by holding down R3+L1+R1. Options are: Max Performance (everything set to max frequency, uses the most battery life), Normal Performance (scales frequency according to load), Power Save (lowers all frequencies to minimum for max battery life, useful for GBA and below). Recommend enabling threaded video in RetroArch for Power Save mode, or change emulators to less demanding ones.

- SafetyNet fix, present as Pixel phone: for fixing TMNT etc (Activated by toggling Magisk > Settings > Enable Zygote and reboot your device). Ignore any warning about additional setup required, this is a false flag. Magisk is working fine.
Other Information:
- RetroArch hotkey: (RG405M) Home/Back button / (RG505) Select Button
- RetroArch menu toggle: (L3 + R3). Choosing the
Close Contentoption closes the game and goes back to Daijisho - RetroArch shortcuts (Hold hotkey down) + L1 = Slow Motion | L2 = Load State | R2 = Save State | R1 = Fast Forward | X = Show FPS | Y = Screenshot
What’s missing:
- Built-in button to on-screen mapping software, alternative solutions can be found in app store.
