Cannot get chd mame games to run

I use programs like Altep Salamander and PowerGrep, which Duimon introduced me to, to do all that stuff easily… but it sounds like you have it all figured out now. Good luck with it.

Those look like solid programs. Thanks for mentioning them. Someday I’ll probably look into that! I actually finally found a full 0.139 CHD set to match what I have, and loaded up a game just fine, so I’ll roll with that for now. Thanks!
