I should rightfully be mocked for not knowing this or not having read whatever faqs I should have to find out, but while I've got you here... I've been using MAME primarily for arcade games and other emulators for other games, SNES. Take SNES... Does Mame work as well running SNES roms as it does running arcade roms or am I better off using stand alone emulators for other formats (like SNES)?
I understand your point about .185. I'm still new here and I'm not how far I can go discussing rom acquisition, but the way I'm going about it is I'll apply updates to the older build. Speaking of which, can I just copy/paste the updates over the top of the older but complete set? Does it matter if the complete set is split, merged, or non-merged? I would think the updates would also have to be labeled, or it is assumed updates are split?
