Re: Zeddy emulator for ZX Spectrum
It made me think about the ZX81-emulator. I already made a new version that never was released and will never since the code is slower than the original due to contented memory. However if I alter the location of the emulator and set supporting routines in contented memory I will be able to win spe...

Re: New 1K hires game in progress: Artillery Duel
Ok, minimal gameplay now working.
Still a few alterations needed on collission.
No bytes left, so seeking optimization before changing the display.

Re: Xtricator - ZX81 Emulator for the Sinclair QL by Dr Carlo Delhez
Isn't patching an option? First check if used ROM is altered. From documentation this should be done only for the DAA instruction. Is replacement of the ROM not enough? Just load that ROM instead of ZX81ROM. Does Dragon Lair use a specific hires method? WRX with 6K buffer and setting of IX only sho...

Re: Xtricator - ZX81 Emulator for the Sinclair QL by Dr Carlo Delhez
BTW, SAM2ZX81 supports also hires from WRX and even some more.
Display kicks in when uppermemory is called and displayed on screen, although slower than real ZX81.
Don't know about the speed of Xtricator and hires together.
Lowres can come close to real speed with some tricks, but hires??

Re: New 1K hires game in progress: Artillery Duel
Finetuning the last steps.
Shot left and right working, but calculation of Y-height is a problem to figure out.
It will be a small adjustment, will find it out.
Memory left: 0 bytes!!!!!

Re: Zeddy emulator for ZX Spectrum
Thanks a lot for your time dr.beep explaining all these, the info so far is quite illuminating! :) I just thought that it would be much simpler for a pure software cycle-exact emulation between the two machines... :roll: The interfaces from Paul Farrow do not emulate, but run the original code on o...

Re: New 1K hires game in progress: Artillery Duel
Loaded cannon was shown and fired after input from angle and speed. Now shown before input, indicating who's turn it is. Just a few things to do, set correct start, read next value in shooting loop, test out of screen, test hit restart game. All can be done in max 10 bytes, I think. 28 bytes left (a...
