Hi, I've been thinking about a 2600 version of Qix for quite a while, but I couldn't find a good solution. Then Manuel pointed at JezzBall, a more simple version of the Qix idea, which was part of M$ Windows Entertainment Pack. The attached file is a very basic proof of concept conversion of JezzBall for the 2600 called JtzBall (Jtz is my shortcut :-). There are still some problems to solve and IMO the game flickers far to much. But I'm only using one of the players until now, using the second player looks very possible and should reduce flicker a lot. The main problem is, that I'm running out of time, when computing the atom/playfield collisions (~260 cycles/atom!), which alone would consume all offscreen time with 20 atoms. And I still haven't done the atom/atom collisions and the Y-sorting of the atoms for the kernel! Compared to the 49 possible atoms of JezzBall on a 28x20 grid, JtzBall should have up to 28 atoms on it's 16x20 grid. The demo shows only 8 atoms, the limited RAM should allow about 20..25 atoms (2 bytes each). So there are still a LOT of problems to solve and I'm absolutely NOT sure, if I can make a game out of this. Have fun!
