I found a workaround with the .srm files.

Open the game you want to use it on before copying over your saved data. Try to open a saved game. This creates a .srm file associated with the game file. Overwrite the .srm file with the desiredsave file.

I do not know why this works. It does though.

@mitu said in Using external DVD drive to play original game (not ripped):

Dreamcast uses GD-ROM as disc format and I don't think it's supported right now by RetroArch

I confirm it's not supported, in the first place no normal CD-ROM drive can read them.

@tb-1599 lr-pcsx-rearmed supports PBP files which essentially smush multi-disc games into a single file.

ETA Prime made a great video that does a great job of explaining how it all works.

I would be more than happy to help you put together your gift. it's really thoughtful of you and cool that your mom would dig something like that.
