I swiped the one from mame. It seems to boot OK but I still have a few issues with the colors. I will keep working on it and hopefully I can figure it all out. Thanks, Kevin

I am implementing Centipede in an FPGA and I am having a problem. I have looked for the exact RNG algo. for 2 days now but I can't find it. It would seem that when Centipede runs, if the RNG does not produce proper results, it resets. I get the thing to go into attract mode sometimes but not very often. I am pulling my hair out. Also, it seems as though the color ram is based off the RNG??? This is a learning exorcise. I have never worked with a 6502 or anything Atari before. But, I think once I get this problem straitened out, I should be on my way. Anyone have the *exact* RNG algo? Thanks, psycho
