Unusable zx Spectrum Emulator (use)

[xxl]

Hi

 

i wrote zx spectrum emulator on atari 8 bit (USE)

 

try run this on zx spectrum:

 

http://pouet.net/prod.php?which=1995

 

run on atari8bit work like this:

 

http://atari.pl/use.avi

 

speed 10% but in other program over 6% of real zx spectrum

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

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?

i locate on zeropage virtual z80 procesor, interprete z80 code from .sna zx spectrum format and update z80 register (on page0). antic display videoram zx spectrum, emulate kempston. no sound... yet

.sna - for spectrum

 

.obx - for atari

Great stuff to see the emulated Z80 code running. Even at 10% speed it's an impressive achievment.

Crazy stuff really ... that is somewhat cool!! Now we can rule the Specci users @ the Forever8 demo party in Trencin/Slovakia :-)

 

next thing is a full c64 emulator. the sid emulation works already *ggggg

I'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

Your emulator looks like it's running faster than the previous version, have you optimised it further? Great work Can you set the background colour to black on future compile regards.

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?

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.
