I am a fairly new MA user but the install & setup is pretty straight forward and I had no problem setting up the official 2.09 version. My problem is that I installed the beta 4 version, told it my mame paths and when it scanned the roms, it only found like 180 or so out of thousands?? I have every rom for mame version .123 so I can't figure out why their not showing up. I am using mame .125 u3 (compiled with hiscore_dat & cpwizard patch), and I have both the command line mame & mame UI .125 u3 installed in the same folder. MA is using the command line version which sees all the roms fine if I run it outside of MA. I did force it to rescan the roms. Does anyone have any idea? This is probably not a bug but I posted it here anyway since it pertains to the new version and I didn't see any setup reasons for it not working.
