I recently became aware of the EGO mod that has been available for many Williams classics. Apparently @jrok found it and implemented it in his FPGA board, then discovered an obscure but nasty feature that changes RANDOM bytes in memory if checksum changes are detected. Could be a harmless glitch or could crash your game. He fixed it by moving the check into unexecuted code, but only on his custom ROM.

Is a fix to the EGO ROM (Joust ROM#5) available? I don't think there is, and I couldn't find it. @steph , do you know of such a beast?
 
I did all the Williams games. See the link in this post:

 
Awesome, Matt - thanks for doing this.
