• Storage: 500 MB for base application; additional space for ROMs and BIOS files.
• Peripherals: USB gamepad or Bluetooth controller (e.g., 8BitDo, Xbox, PlayStation).

Troubleshooting RetroBoot 1.2.1: Common Issues

Even a stable build has quirks. Here is how to solve them.

Issue: "USB drive not detected."

• Fix: Make sure the volume label is SONY. Re-format to MBR partition scheme (not GPT). Use a 2.0 drive under 128GB.

Issue: Games crash when returning to menu.

• Fix: This was a bug in 1.2.0. Verify you are on 1.2.1. If the problem persists, disable "Rewind" and "Run-Ahead" features, as they strain the PSC's memory.

Issue: No sound in SNES games.

• Fix: Switch the core from Beetle Supafaust to Snes9x 2010. The audio driver in RetroBoot 1.2.1 conflicts with Supafaust on certain TV sets.

Issue: Bluetooth controller not saving pairing.

• Fix: In RetroArch, go to Settings > Drivers > Input driver and change it from udev to linuxraw. Pair your device while in the menu, then use Configuration File > Save Current Configuration.

Upgrade notes & recommendations

1. Backup your configuration and custom ROMs before upgrading.
2. If you use custom audio drivers, enable Settings → Audio → Legacy Audio Mode after upgrade.
3. Reimport controller mappings if they reset.
4. Verify third-party plugin compatibility; update plugins to latest releases.

2. "My PS1 controller isn't working in-game."

• Fix: In RetroArch, go to Settings > Input > Port 1 Controls. Map the controller manually. Save the configuration as "Autoconfig." For wireless adapters, ensure they are plugged in before booting the console.
