: Point your emulator to the folder containing the ROM pack. Most will scan subfolders automatically. How to Handle Multi-Disc Games (e.g., Final Fantasy VII, Metal Gear Solid) Option A: .m3u playlists (recommended) Create a text file with .m3u extension listing disc file names:

Final Fantasy VII (Disc 1).chd Final Fantasy VII (Disc 2).chd Final Fantasy VII (Disc 3).chd Load the .m3u file in the emulator – it will prompt you to swap discs. One file containing all discs. Use PSX2PSP to merge discs. Option C: Separate save states – risky; can break disc swapping. Common Issues & Fixes | Problem | Likely cause | Solution | |---------|--------------|----------| | Game doesn’t boot | Missing BIOS | Add scph1001.bin , scph5501.bin to emulator’s BIOS folder | | No music in racing/fighting games | Missing .cue or wrong track offsets | Redump-correct .cue sheet | | Game runs too fast/slow | Region mismatch (NTSC vs PAL) | Set correct region in emulator | | Corrupted graphics | Bad dump | Check ROM hash against Redump database | BIOS files are not ROMs – they are copyrighted system software. You must dump them from your own PS1 console. Storage & Organization Tips for Large Packs A full US PS1 set (Redump) is ~1.2 TB as .bin/.cue , ~600 GB as .chd .

Missing .cue = audio tracks may not play (no music in some games). | Emulator | Platform | Best for | ROM pack format | |----------|----------|----------|------------------| | DuckStation | Win, Mac, Linux, Android | Accuracy + ease | .chd , .bin/.cue | | RetroArch (PCSX-ReARMed) | Multi | Retro gaming handhelds | .pbp , .chd | | ePSXe | Win, Android | Older hardware | .bin/.cue | | SwanStation (RetroArch core) | Multi | Modern accuracy | .chd |
