: Multi-disc game doesn’t prompt for disc 2. Cause : Emulator missing disc swap config. Fix : On PSP: press HOME → Disc Swap → choose disc. On RetroArch: Open Quick Menu → Disc Control.
Multi-disc games: Modern tools (PSX2PSP v1.4.2 or pop-fe) can embed disc 1, disc 2, etc. as separate “discs” inside one PBP – the emulator asks you to swap at runtime. | Feature | BIN/CUE | CHD (lossless) | PBP (lossy possible) | |---------------------------|----------------|----------------|----------------------| | Compression ratio | None | ~30-50% | ~40-60% (zlib) | | Multi-disc single file | No (multiple files) | Yes (M3U + CHD) | Yes (native) | | Metadata embedding | No | No | Yes (icons, title) | | Streaming from storage | Slow (random) | Fast | Moderate | | Emulator support | Universal | Growing (RetroArch, DuckStation) | PSP, Vita, RetroArch, some Android | | Lossy audio possible | No | No | Yes (convert CDDA to ATRAC3) | roms psx pbp
