MAME4ALL Dingoo currently emulates lots of arcade games supported by original MAME 0.37b5 plus some additional games from newer MAME versions. Some larger games currently do not work due to lack of system RAM.
The problem with X party blocked X bill that would have prevented X is that yes the bill probably would have worked great, buuuttt they put XYZDCBG in said bill as an attempt to sneak things in that tend to be completely unrelated to the original bills intent. It sucks because if they would just do a single thing they could probably get something done...
