Uhh.. I tried once but I don't know where to start. DTR is down so I can't refer to that. I'd have to take loads of screens to make my own conversion.
Also, I don't know how to do the Masking bit.

Also, is it possible to get the music from the PC version in MOD, .IT or whatever format is usable in JCS?
