I was previously using a mapped drive to access my ROMs on my NAS in GameEx but due to that causing problems elsewhere on the computer (the "Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed" error whenever I tried to access a different share while the drive was mapped), I've switched to using UNC paths now to access my ROMs. This works for the 6 other emulators I have installed in GameEx but not MAME - any ideas why this could be? And is there a fix? I tried writing a batch file to map the drive before GameEx loads and then another batch file to disconnect the drive when GameEx shuts down but even that doesn't work - the 'net use' command only seems to work when I enter it manually at the command prompt and not in a batch file, even though I'm entering the exact same command! EDIT: also, I have a second MAME config question - I would like to map two of the buttons on my Microsoft Sidewinder Game Pad USB to 5 (insert coin) and 1 (1 player start). Is it possible to do this for MAME only? The Joy Mapping section in Advanced Emulator Config and the custominput.ini file appear to edit joypad mapping globally for all emulators...
