As a recovering Z80 addict I hope this is the last assembly language program I will ever write. I don't believe this particular effect has ever been done before, and I don't believe the bog standard 48 has ever been pushed this hard. I'm ready to be corrected on these points though. http://sites.google.com/site/andrewowennet/zxodus.zip Enjoy. -Andrew

It does a 144x144 pixel 8x1 attribute area on the bog standard machine.

Sorry, beat you to it 5 months ago I'm afraid :-P http://www.worldofspectrum.org/forums/showpost.php?p=522051 You're the first to get it up and running with 48K timings, though, I'll give you that...

Ok Matt, you demonstrated the principle 5 months ago, but did you do a demo that used it?

Good stuff. Is it a Speccy? Is it an Amstrad? No, it's ... yes! Given the nature of the graphics you chose, do you think it could work in a turn-based, tile-based game? Maybe a cool multicoloured Speccy NetHack :) Eq.

I think a turn-based, tile-based game is just the right thing to do with it. It's annoying that it takes 27 interrupts to redraw the tile map, but that's all the poor machine can manage and still have enough CPU cycles left over to do anything else.
