Title: Splitting rom files
Post by: RVVD4029 on March 31, 2015, 02:27:40 PM

How to split a multicart into separate rom files. I want to play the games on other consoles.

It's actually pretty hard to do

I don't know exactly, but i think you have to do something like this:
1. Split rom into PRG and CHR parts
2. Cut all unnecessary information with HEX editor from CHR and PRG parts
3. Change all that it needed to make it work on another mapper. Again by using HEX editor
4. Build new ROM.

Yeah, it's not easy - it depends on the game and the multicart, but basically you have to locate the PRG and CHR banks for the game you want to extract, stitch them together and give it an appropriate header - if you're lucky it will work on a standard mapper but otherwise you might have to do some hacking.
