@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. aguilera.john@gmail.com feel free to drop me an email. I have many resources that can help you.

I've been considering compressing roms lately as I keep them uncompressed for all systems to prevent SD write cycles from extractions. These wouldn't extract or cache whatsoever, right? Also does RetroArch cache from my current .bin's and .cue's to "/tmp/Retroarch/"? I've been considering changing RetroArch's tmp to "/tmp/" (a RAM drive) but that would choke a pi3 if it tried to cache a PSX game, thus I'm trying to trim them without the need of extraction.

@mediamogul Awesome, thanks for the clarification.

@blackshadow Interesting. From everything I read on pbp files it only costs a bit of load time because of the format. I didn't consider that the compression would affect it as well, considering the fact that I'm always playing SNES and GBA games still zipped and have never had an issue. That said, I do plan on sticking with pbp files for multi-disc games since the 30% compression I get from it will help save space on my SD card for more games in the future

@affleck001 Add more details about your system - https://retropie.org.uk/forum/topic/3/read-this-first. Start the game in RetroArch with the .m3u file and verbose logging enabled through the Runcommand menu (https://retropie.org.uk/docs/Runcommand/) and then get the logfile from /dev/shm/runcommand.log and upload it to pastebin.com to take a look at it.

I would recommend converting your .bin files to .pbp. Once done, follow the video tutorial on how to swap discs. You can then assign hotkeys (button combination with your assigned hotkey) to swap the disc without needing to open the retroarch menu every time for that game.

@mediamogul Thank you for your advice. I will try both method. Have a great day~
