I have a swemmer Gottlieb 80 mpu board. I want to burn new roms to use it in a black hole game. I have the rom files and need to burn them to new EPROMs. I got the prom1 done. But now how do I burn the two separate U2 and U3 files to one 2764 eprom for use in the swemmer board? I must have to combine rom files some how? I’m using a GQ 4-4 burner. Any help much appreciated.

Peter, Thanks buddy! Thank you for dumbing it down to something I can understand. I was able to combine files...I think. I created a new file but I have yet to see if it works in the game. Ill report back if the game does indeed boot.
Thanks for the help!
