Hey folks, long time no see.
Since I have nothing else to do... I'm updating my cabs for the first time in 5+ years. I haven't been here in a while either, so it was nice to see the All Killer No Filler lists. Maybe I'll do a version of these for special controls...?
Anyway, for those folks who are starting new and fresh, I've run BadMouth's original _NoFiller.txt batch file against Mame .222 and the only game files to throw errors are crimfght2.zip (replace with crimfghtu.zip) and vendetta2.zip (replace with vendetta2pw.zip or whichever version floats your boat.)
All other errors are BIOS/devices related, about 8 instances. Most have just been renamed, and can be tracked easily enough with mameinfo's NEWS.txt. That said, if you're working with these newer versions of MAME, there's a BIOS/device subset out there that will distinctly simplify the process at a minimal 240MB space premium. Just copy that over after you've done NoFiller, and you'll be good to go, especially if you're thinking of adding any other games later in the process (no need to think about dependencies when they're all already there.)
