WinUAEX Final? version released (with source)
For anyone who's interested XPort has now released a final batch of emulators, mostly with only GUI fixes, one of which includes WinUAEX.
It's a great port of WinUAE and I've had a lot of fun out of it.
He's also released the source for each and every one of his emulator ports so that anyone who wishes to take over any of his projects can do.
More info is over at the xbox-scene forums.
