MAME is inevitable, Mister Anderson. (WIP by Olivier Galibert).
TSCHAK: hopefully the machines you can get to have different ROM versions. CHM's is 1.07 so there's plenty of variety. And dumps of cartridges would be welcome.
And yeah, will work with the machines that are here in DFW to get ROMs. The massive excavation and liquidation at Computer Reset has been happening for the last couple of weeks, and two and a half units have been found so far, there may be more.
