I tried knights of valour which is a pgm game. seems to run alright but game itself didn't seem to be that great. I don't know if the other pgm games are any good.
[Emulator Guide]
use gngeo2x for neo geo games unless you have problems (sidekicks games, turfmasters, overtop for example) then try fba2x for ones that don't work. If it still doesn't work go for mame4all which has compatibility with tons of games but runs the slowest out of the three. sonic wings 2 and overtop are two games i only got to work right with mame4all.
for other games:
cps2: I'd personally use the dedicated emulator for that. you need cache files which fba2x doesn't need but seems to run best with that emulator and has more options and things like save states. though fba2x is still a good option and some prefer it due to not needing cache files (except some larger games maybe like i think the D&D games). Either way is good I mainly prefer the cps2 emu for save states.
cps1: fba2x all the way. runs fast as needed at 200. though mame4all will give you more options as its got pretty much all the mame features even things like game history if you have the file there. It does take a while to load but its there.
toaplan, cave games: fba2x
anything else: fba2x if it supports and works. mame4all if it doesn't. as mame4all is a pretty complete port it has tons of options if thats what you need.
hint: If you have problems with games in fba2x or gngeo2x especially sound problems you usually have to run them in mame4all with only the cyclone core which makes things slower.
