I put the first version of the Atari 7800 signing program up for people to try:
http://www.dsplib.com/a7800/a78sign.zip
Usage: a78sign [-c] infile
-c indicate check mode only
default is rewrite if invalid
Warning: Be careful, it might corrupt your rom images!
I'm still having a bit of trouble with that one byte in the hash, but I'm brute
forcing it for now. This means my sigs are not necessarily the same as Atari
sigs. If you modify a virgin cart image, re-sign it, unmodify it, and re-sign it
again - the signature will most likely be different.
My testing consists of: I've modified asteroids and it loads in the emulator.
Thanks

P.S. Keith, I credited you in the code - your code was the basis for the
checksumming, the file reading, and the P & Q extraction.
