Thanks a lot for taking the time, Styphelus. I have a clean BigBox setup that I like, with some MAME 0.194 roms. Not all, just a trimmed down collection. I am just about to finish downloading a MAME CHD 0.185 collection and was wondering if I'll get some benefit by adding the CHDs. I can figure out the technical part of it and probably make it work, just not sure if it's worth the hassle. I mean, are the games better? Are MAME 0.185 non merged and MAME 0.185 CHDs the same games, but with more...information (video, sound)?
