Re: Stuffs to read before going to bed

although perhaps not very well suited for reading before going to bed! It's the kind of article that keeps you up late because you just can't stop reading. :) Thanks, Charles, for your comments. The article is subject to continual revision, and I think you'll notice some improvements in clarity and...

Re: 2011 Code Competition.

the restriction is that you have to keep your ROM under 70KB. we are very flexible with space (especially with HuC) so dont let that be a limiting factor in your work but keep it small!

Check the original post at the other forum for an update and some clarifications.

Re: Technical References

Wow! I bought the Ferraro book "Programmer's Guide to the EGA, VGA, Super VGA Cards", Abrash's "Graphics Programming Black Book", and had an ASCII reference to the VGA card from IBM back in my VGA programming days.
