Lantus, this is awesome. I was JUST configuring my friend's mame360 and then deleted it from my own jtag because the only game I wanted to play on it was MK (most of my other stuff works in FBA), and the sound was very low and there was input lag so I just said "I'll wait" - your post was SO on time (even as just a "coming soon").
Do you have testers? I've jtagged a good ~40 units (some on x-s; most locally). I can test on xenon and falcon personally, and possibly ask a past customer (local, for accurate communication's sake) to test a zephyr or BB Jasper (if I can't dig one up myself).
Either way, glad to see this project revived, especially for the sake of perfect MK emulation
You are a gentleman and a scholar, as well as a prince among men!
