cas Posted February 20, 2007 Share Posted February 20, 2007 Impressive. Do you interpret the Z80 binary code to 6502 subroutine code, or do you use some kind of "Just-in-time" compilation? Would be nice to run CP/M on the Atari with that Carsten Quote Link to comment Share on other sites More sharing options...
Gury Posted February 20, 2007 Share Posted February 20, 2007 Great idea. It is interesting to see on what extent it is possible to emulate ZX Spectrum on Atari 8-bit computer. Is your emulator ready and available to download? Quote Link to comment Share on other sites More sharing options...

Tezz Posted February 22, 2007 Share Posted February 22, 2007 Great stuff to see the emulated Z80 code running. Even at 10% speed it's an impressive achievment. Quote Link to comment Share on other sites More sharing options...
twh/f2 Posted February 22, 2007 Share Posted February 22, 2007 Great stuff to see the emulated Z80 code running. Even at 10% speed it's an impressive achievment.

Tezz Posted March 11, 2007 Share Posted March 11, 2007 http://atari.pl/emulator.rarI'm really interested in your emulation project. How far have you developed it? will it run only selected programs so far? Have you started any 816 optimised version yet? keep up the good work Regards, Tezz Quote Link to comment Share on other sites More sharing options...

Great work Can you set the background colour to black on future compile regards. Quote Link to comment Share on other sites More sharing options...

Gury Posted April 23, 2007 Share Posted April 23, 2007 Many thanks for your effort xxl, even the emulation is 10 - 20% of original thing. Maybe we could consider these games as new games for Atari, even if they are just emulated. What do you think? Quote Link to comment Share on other sites More sharing options...

Tezz Posted April 28, 2007 Share Posted April 28, 2007 update: http://atari.pl/zxemul.rar - faster sir lancelot jetpac deathchase pheenix Your project improves all the time and a really noticable improvement this time Really good stuff. It's a very impressive speed considering our little 6502 is emulating not only the Z80 code but the Spectrum specifics too. Quote Link to comment Share on other sites More sharing options...
