I hacked the loader to use ProDOS MLI calls in order to run HBCC under

 Just out of curiosity, when it runs on something accelerated, e.g. a IIgs
at full speed or something with a Zip Chip etc. does it run faster or with
a higher framerate?

It does run faster, but the joystick code whacks out. If your accelerator can slow down during joystick address fetches, it should function OK. You can disable the joystick with the J key (CAPS LOCK) and use the keyboard controls. However, the timing is based off a 1 MHz processor, so everything gets accelerated, including the movement of bad guys and time. It runs at something like 200 Hz on my 9 MHz GS. Kinda useless. There really isn't any generic mechanism on the Apple II to establish a consistent timebase. If everyone had a mouse card it would solve that problem, but not everyone (or every Apple II) does.
