I've just uploaded Atari800-0.5.0.tar.gz onto my web page
located at:-

You can also obtain an Amiga binary version at the same location. It
requires an A1200. The Amiga version is currently 0.4.5. If you've
got a C compiler and the resources you should be able compile 0.5.0
yourself - Hopefully I'll be able to upload a new binary shortly.

Changes in 0.5.0

- Simplified interface to CPU module.
- DIRECT_VIDEO now works with PMG collision detection. This option 
  increases performance by about 28% but can result in different colours
  being displayed. This is because this option relies on COLPF0, COLPF1,
  COLPF2, COLPF3 and COLBK all having different values, hence the
  emulator sometimes modifies the colours :-( This option can be enabled
  during the configuration phase.
- Correction to ANTIC Mode 5 Vertical Scrolling.
- Correction to PMG DMA Code - Demon Attack now works OK.
- Added code to limit the emulator to 50fps - this will not have any
  effect if your machine can't run the emulator greater than 50fps.
  F10 in X11, XVIEW, MOTIF and SVGALIB versions toggles the limit
  on/off. When the limit is off the emulator will go as fast as it can.
- Path to directory containing the OS ROM images is now defined during
  the configuration phase (Declaration of ATARI_LIBRARY has been removed
  from the Makefile).
- Correction to handling of PMG DMA - Pitfall II now Works.
- The unused bits in PMBASE are now ignored correcting errors in Atari
  Chess and Frogger.
