Ah, cool, that's great news!
BTW, I have a suggestion for the next HAS-rev:
an extra button for entering the button-remapping mode - I guess this can be useful for those who don't have NeoGeo/generic arcade controls (like me atm) and use adapters that need some time to sync with the controller.
I am using the UD-USB decoder and I couldn't enter that mode (even with a wired PS3 dualshock3)... found a workaround though as I first connected a different controller (tototek PS1 to NeoGeo), entered the remapping mode and then unplugged and connected the HD-USB.
