I wish you good luck with this. I went through that in 2007/8 already with limited success. Getting the games to boot is easy. The checks can be NOP'ed out using IDA Pro and the M2 plug-in. But there's much more to be done. You can't trigger "insert coin", nor do you have player 1/2 start buttons on the kiosk. Also, the code will fail to read the dip switch settings. I gave up - knowing that I'll never get any game past the attract mode.
