Hi, first post, so apologies if this is the wrong place or if I've done anything else wrong.
I did try searching the site, and even the internet as a whole, for information on this topic, however I couldn't find a solid answer.
I was wondering if it's possible to swap out the music in the US release of Sonic Gems Collection for Sonic CD for the Japanese files to use the original Japanese/European soundtrack, but with English language text and such.
I would just use the Japanese version, but I'd prefer the English text and translations. I don't care about the extra games in the Japanese release as I have other ways of playing them.
I've gotten as far as extracting the CVM file which contains the music and video files, however a straight swap of the Japanese version with the US one freezes Sonic CD on selecting the game, and while I can extract both the AFS audio and SFD video files, I can't seem to work out how to recompile them into the ISO, if that's even possible.
I know it may seem like a pointless project, but I think I'm just wondering if what I'm trying is even possible, and would gratefully welcome any input from people who may have a better idea of where to go from here.
