It looks quite nice running and is definitely fast enough to work on fba-xxx. There are a few things holding up a release (save states, easier interfaces for the new cpu cores, etc). I've even ported a fairly popular (and insanely difficult) game using the new m6809 core. Which game would that be i wonder? You've already got that it's stupid hard, and runs on an m6809. I suppose I can give you one more hint -- it's made by konami.
