i got it to get 210$ with 44100 sr and samples=no but not farther than that. GERMAX: please TEST your recordings before submiting them or you'll be contributing a lot of junk to marp. I suspect you have to record with frameskip=0 and NO sound.
You'll need the old rom and an early .36 beta mame to have any realistic chance of recording and playing it back. It's the same system as 720, Tommi and myself can vouch for the pain in the ass that is to record!
