MAINBOARD IDENTIFICATION

Different mainboard versions have specific characteristics. Here's how to identify them:

Original R36S Mainboards

  • R36S-V12 - Early version, 2 RAM chips, full CFW support
  • R36S-V21 - Current version, 2 RAM chips, best compatibility
  • R36S-V21 2024-12-18 - Latest revision with improved panel support
✓ All original versions support ArkOS, AmberELEC, ROCKNIX

Clone Mainboards

  • G80D-MB V1.0 - 2 RAM chips (looks like original), requires ArkOS4Clone Panel 10/5
  • G80C-MB V1.1/V1.2 - Single RAM chip, EmuELEC based, requires ArkOS4Clone Panel 8
  • RF35XE-MB (K36) - Most common clone, single RAM, ArkOS4Clone or ArkOS K36
  • GB350 / V2.5 - Uses RK3128 chip, NO CFW SUPPORT, avoid!
⚠ Clone versions require specific firmware and DTB configurations
How to Check Your Mainboard
  1. If your device has a transparent case, look for the text printed on the mainboard
  2. Count the RAM chips visible on the board (1 chip = likely clone, 2 chips = likely original or G80D)
  3. Use the DTB Analyzer tool to identify your device's panel configuration
  4. Check boot behavior - clones often show "God of War" logo or EmuELEC text
Go to DTB Analyzer

RAM DIFFERENCE IMPACT

Original: 2 RAM Chips

Clone: 1 RAM Chip

🔍 How to Check Your RAM ▼

In RetroArch, go to Main Menu > Information > System Information. If you see 497MB instead of 1GB, you have a 512MB RAM clone.

1GB RAM (Original & Some Clones)

  • Good PSP performance for light games
  • Dreamcast 2D games playable
  • Most N64 games work well
  • Smooth RetroArch operation

512MB RAM (Most Clones)

  • PSP games mostly unplayable
  • Dreamcast severely limited
  • N64 has frequent crashes
  • Some PS1 games may have issues
  • RetroArch may crash with heavy shaders

256MB RAM (GB350/V2.5 Clone)

  • Only basic 8/16-bit emulation works
  • No CFW support
  • Avoid this variant completely!
