I just wanted to share with you my current project. I modified a Donkey Kong 2600 rom to look more like the arcade version. I'm fond with how it's turning out, especially Mario's sprite. I hope you enjoy playing the rom!
(Note: There is a glitch with Mario's hat if he jumps at the top of the first level. I hope someone can try to fix that).

I've noticed that the maze colors are off. I made a rom with more acurate colors, and made some minor graphic changes. I've attached it to this post, along with a pic that compares the arcade PacMan with the homebrew and to my hack of it.

Pretty good. I'd love to help implement physics, although I have no idea how to, but that's probably because I've never tried batari BASIC before. Although, I DO know how to edit graphics and palettes.
