Documentation, anyone? Hardly anything other than the revision history and JIT compiler is covered in the docs. For shame.
I've had all kinds of problems with the latest version. I can't get it to work with my own ripped A1200 3.0 roms, and a bootleg 1.3 ROM will only get as far as the disk-insert boot screen and then it crashes, sometimes taking all of Win2000 with it (WinUAE is the only application I know of that will bring Win2000 down!!!)
I'm sticking with 8.26 for now.
