All official games are * old * CHD versions of GDI files. Sega Dreamcast - Near Complete US set, with a good amount of JP games. Panasonic 3DO - Near complete US set, all in iso format ā 76.8GB Some of these are in bin/cue and others in iso/cue. NEC Turbo-Grafx-CD - Complete US set, with a bit of JP games. TL DR ā I need to compress the bejesus out of my disc games, CHD seems like the way to go, how do I do this for each system to get into the new chd format, and also how to convert the old chd format on DC to the new.
UPDATE - I have compressed these files, update post at post #26 in this thread contains results! Iām in DIRE need of space, and the OCD in me needs to get a standardized file-type on some of these systems.
