Having a single file for your multi-disc games is possible. Just create an eboot file containing your iso, bin, img images via the free software psx2psp.
We remind you that you must have your own PSX disk images !
Convert button, then wait.Place your folder or rename the eboot file created to your recalbox in the /recalbox/share/roms/psx folder.
To change CDs during the game, you need to activate 2-3 options in the RetroArch menu.
Hotkey + B.From this point on, any changes you make in the options will be saved when you exit the RetroArch menu.
When you will be on the screen of a game asking you to change CD, you will just have to virtually eject the CD (by doing hotkey + the shortcut assigned to the disk eject toggle option), to change cd, and to virtually close the cd drive.
Your game will then start automatically on the next CD.You can consult this thread on the forum in case of problems.
Method for .bin files
Hotkey + B./recalbox/share/roms/psx) with disk image append.When you convert a game to .PBP format, the format of this file will change the alignment of the tracks on multi-track and/or multi-disk games with the conversion program (usually PSX2PSP). If you ever want to go back, there is a risk, if not more, of ending up with badly truncated or overlapping tracks by reversing the process.
When it will re-trim the tracks to .BIN/.CUE, it will usually cut 2048 bytes too far. So, you have a piece of track 2 in your track 1.
The problem happens with track 3: you have a piece of track 3 in track 2, but offset by ... 2x 2048 bytes, and so on.
The quality of the dump is still there, but you'll cut it anyhow, and the PBP headers don't allow to recreate the .CUE faithfully, nor the track markers (LEAD IN/LEAD OUT).
It is faster to dub your record again than to try to correct automatically or by hand.
