I'm just sharing my progress in the game I've being working for a few months...
The inpiration/motivation came from the movie Tron with that light cycles racing game, later on I played one called ktron for Linux (does anyone know it?).
I found it would be a good starting point to do it in Assembly (I've always wanted to have a change to learn this programming language), so now I had a good reason, why not?!
Don't know why I got surprised, but I found that they already had developed a similar game called Surround and that was done right after Atari 2600 was release, that was awesome!
Anyway, I think it is still a good starting point for me, and maybe I could do it a little differently...
As soon as I get a playable release, I'll put here the roms, source code and everything... And of course, specially my questions on how to do it better and better...
