Hi there,
The megadrive is on my list of platforms to tackle too :)

I've not tried it yet, but this emulator runs on windows/linux etc and has an integrated debugger. Debugging through an emulator on a modern PC is breeze compared to the tedium of the old days!

What video card does it have (CGA,EGA ,VGA.. etc)?

Hey Stenlik,
I know nothing about the Vic-20 so I've been reluctant to wade in. Hopefully your issue is more generic than that..

I assume $9004 is being updated during a scan line interrupt (or horizontal blank). This is the fraction of time it takes a CRT beam to finish at the right hand side of ...

Hi all,
I can't believe it's been a full year since I posted my software sprites demo!
(It's been an interesting year, one in which all my work dried up and I almost sold off my entire retro collection to fund a new business venture. But I didn't, and things have improved massively for me in the ...

Hey all,

I just wanted to let you know that I'm tinkering away at my background code and tools for a new game project and the first stage is almost done -- a 'software sprite' system.

Very cool. It's nice to see it running on real hardware - even if that is the most unorthodox mouse position I ever saw
I'm not doing ST stuff at the moment so thanks for the youtube version

I've just used these to print a scan of 'Mapping The Atari 2nd Edition' and it's pretty neat. A5, 308 Pages, ring bound with a protective plastic cover front and back. It cost around £15 + £2 delivery. Ordered Friday afternoon and delivered Wednesday morning.

Really impressive Colin. To build the interface for a 'foreign' machine and then code the magic to make it run deserves a special applause. I'm in awe! And to still code on original hardware.. I really admire that (I haven't been able to bring myself to do it since someone *ahem* packaged up a shit ...
