ok, fixed the categories.
i must have more roms that mame officially supports. these roms are listed in the 76 catver.ini file from catver.com, but they dont have a category listed next them.
thus they show up in any category.
i fixed this by changing the blank space in the catver file to something like "notcategorized" or something along those lines.
i then made a seperate category just for those troublemaking roms, incase i ever want to access them.
now categories work great. mamewah rocks.
one more question, though. I am using mamewah for snes as well. not all of the games are zipped, though. is there a way to include more than one extension (zip, smc, sfc) in mamewah's options? or do i need to somehow zip each (~300) file?
Thank for the help,
Ryan
