Test7800 v0.6.3 is released. Test7800 is an experimental emulator for the Atari 7800. It's not complete and is missing some important features but it plays many of the 7800 ROM files that are available. It supports a78 files and will emulate regular "flat" ROM files and also "supergame" ROM files. It does not yet emulate the POKEY chip and similar hardware. The 6502, TIA and RIOT emulation is taken from Gopher2600 and is therefore well tested. The implemenation of the MARIA is new to this project.

Test7800 Changelog:
Audio
sample rate increased to 48000Hz
this improves POKEY audio that uses the 1.79Mhz clock
it's not always noticeable but pure tones generated by this clock can suffer when sampled a rate that is too low
the higher the sample rate the better but 48000Hz is a reasonable compromise value
added -samplerate option to allow setting the value
Cartridge Mappers
Activision mapper (#28)
Absolute mapper (#30)
