| Problem | Likely Fix |
|---------|-------------|
| ISO not showing in menu | File extension wrong (must be .iso, .chd, .bin/.cue) |
| PS2 ISO crashes | Missing BIOS or need to change emulator (Press Start → Game Settings → Per-system advanced config → PS2 → Change from Auto to PCSX2 standalone) |
| Multi-disc games (PS1) | Place all discs in same folder → rename .m3u playlist file → Batocera will show single entry |
| ISO too large | Use CHD compression (reduces size 20-40% with no performance loss) |
| USB boot says "no bootable device" | Disable Secure Boot, enable Legacy/CSM boot, or use Rufus (DD mode) instead of Etcher |
Batocera includes a built-in network file server.
Yes. While the live USB is the main use case, you can install Batocera to an internal SSD or dual-boot alongside Windows. The ISO includes an installer option in the main menu.
