I found by accident an old Reddit post where I learned that you can compress BIN/CUE into Mame’s CHD format which is supported by the Beetle PSX core the result is you will have a single compressed file for each PSX game that is comparable to the original 7zip in size and directly playable.
This took up a significant portion of the 1TB drive I was using to store all ROMs additionally Redump uses separate BIN files for every track on the CD so a single game would have multiple BIN files plus the CUE. The Redump set for PlayStation 1 USA is about 385GB (just the games, no demo/samplers etc) 512GB in 7zip format 7zip is not supported by the Beetle PSX core so when I originally added the PSX library to my Launchbox/RetroArch setup I just extracted every game. I’ve also converted Sega CD, Sega Saturn and Turbo Duo CD games from BIN/CUE to CHD for use in RetroArch. While I originally wrote this with PSX games in mind, you can apply it to most other CD based consoles. Update : Google Search Console tells me this page is getting popular lately.
