Blitzen 0.3
===========

By Peter Gordon (pete()petergordon.org.uk)

Blitzen is a blitter emulator for OS4. It attempts to impliment enough of the
functionality of the classic Amiga blitter to make a few more old programs
run on OS4 systems without the classic chipset (IE AmigaOne).


The following is currently emulated:

 - Ascending and descending copy operations with shift
 - Descending mode fill operations with shift
 - Line mode (not tested)
 - End of DMA interrupt for apps using SetIntVector()
 - The 68k "WaitBlit" function is patched to wait for the emulated blitter

What is not emulated:

 - Ascending mode fill operations (the hardware reference says they don't work
  properly, and I don't currently know what happens if you try it on the real
  hardware).
 - End of DMA interrupt for apps abusing the 68k VBR

You can run blitzen at any time, and quit it with Ctrl-C.
