Hey kids
Here's a little something to play with.
It's a driver.c and mame.mak for mame .86 (that's what it's tested with anyway..)
This only enables the required CPUs and drivers for CPS1, CPS2, and Neogeo games.
Compiled (without a GUI [I haven't even checked mame32]) it's 2.6mb.
UPX'd it's about 750kb.
I'm hope this helps... someone...
btw. Make sure to do a clean build (delete your obj dir)
