Whoa, is this 'langlest' langlest?
No dice for CPS2... Toad King is doing a great job with mame sdl but cps2 isn't supported... for Neo Geo there's Geogx which you should find pretty easily... it's an old emu and rather bare bones, but it does the job.. however any game over 30ish MB won't load due to the Wii memory limitations..
I've personally got my fingers crossed for WiiSX beta2 being able to run the CPS2 conversions pretty well, tbh this is probably our best bet for these games at the moment....
