I haven't use .chd files yet. Are a game with .chd format require more processing resources to run, than bin/cue format?

@thellin1
You could create an m3u index to point to the iso files or even cue, bin or pbp files.

Legend of Dragoon (Disc 1).m3u contents: ./Legend of Dragoon (Disc 1).iso ./Legend of Dragoon (Disc 2).iso ./Legend of Dragoon (Disc 3).iso ./Legend of Dragoon (Disc 4).iso

This way there is no need to append the image, because the index is already there.

If you wanted to go the extra effort, you could create a folder for the game, and then make an m3u index for each disc. that way you will be able start on disc3 if the first entry in the index is disc3.

Legend of Dragoon (Disc 3).m3u ./Legend of Dragoon (Disc 3).iso ./Legend of Dragoon (Disc 1).iso ./Legend of Dragoon (Disc 2).iso ./Legend of Dragoon (Disc 4).iso

Though additionally you would have to symlink all the memorycards to the same one.
make sure there is only the 1 memory card you want to keep and link to: "Legend of Dragoon.srm" and delete the others or else the links wont be made.
ln -s "Legend of Dragoon.srm" "Legend of Dragoon (Disc 1).srm" "Legend of Dragoon (Disc 2).srm" "Legend of Dragoon (Disc 3).srm" "Legend of Dragoon (Disc 4).srm"
provided those are the names for the m3u indices.

You could also use a program called PSX2PSP to convert and compress all of the discs into a single or individual PBP file that can be loaded in EmulationStation.

it has to be a bravia

@TheDataCereal This is probably the easiest method so far. Do you know what a proper m3u file should look like and how the file should be named so the emulator recognizes it?

While that's the easiest, I still think this could be much more user friendly. Not knocking your suggestions at all, but as any classic American infomercial would say, "There's gotta be a better way!"

Hi,

es_systems.cfg is in /etc/emulationstation/.

You can swap discs with your defined swap disc hotkey. Look in input settings in retroarch gui or in the configuration editor:

# Toggles eject for disks. Used for multiple-disk content. input_disk_eject_toggle = # Cycles through disk images. Use after ejecting. # Complete by toggling eject again. input_disk_next =

Put your prefered button after the = . Ingame press your hotkey button and your button eject and swap discs.

In case the answer wasn't obvious, or if anyone is interested. The old save states worked with both bin and pbp files as long as the file names were identical.

You need to find a PSX bios file and put it in your BIOS directory. Try looking for SCPH1001.BIN or
scph5501.bin those are both very common.
