What is a PRG1 rom code?

[Prozak]

I've seen some roms labeled with PRG1 and I was wondering what this code was as it's not listed in the sticky thread, thanks.

PRG Roms are Roms for the same game that have differences. Think of them like version releases.

Okay I can help you understand it better. The PRG ROM loads into memory is broken up into two separate 16K banks or something like that, understand ?
