                         PVCS version 1.3

                   Atari 2600 emu for the ps2


Thanks to Dan Boris and Alex Hornby for the original emu code.
I added Ron Fries sound code and Star Path (AR banking).
Major change to TIA code. The stella TIA code was pilfered (after converting 
it from c++ to C).  Now games like Centipede and Defender 2 work.
The most Star Path games are now playable.

FILES.TXT lists the available ROMS.
Format is:
Game Name,ROM.BIN

If you are making a cdrom make a subdir "ROMS", so this can be selected.
