I think this may be a fairly naive question (for which I apologize in advance), but I've been wondering for a while about extracting and re-encoding assets from Sega CD games. Specifically, there are two projects I've wondered about:
1) Extracting non-Redbook audio from a game (e.g. the "GAME OVER" tune from Cobra Command, which seems truncated on my copy and which I'd like to hear in its entirety);
2) Adding subtitles to FMV content (e.g. the cutscenes in Earnest Evans and Anet Futatabi).
Can anyone offer an approximate rundown of what would be involved in extracting these, and what tools are available? Is there a good wiki (or equivalent) for Sega CD content hacking? Or is the answer basically "it depends on how the disc was authored and how the files were encoded, and you'll have to roll your own tools for almost every project"?
