I'm so confused with this. I have a few 4 player Konami games that force you to one character on the select screen. I was able tick Extract ROM archives before running and that seemed to work with the Simpsons and Turtles in Time. However, the original TMNT games is still stuck on forcing you to pick player one character ( 4 player UK) I read through the Forum and someone suggested merging your own roms. I have no idea how to do that and trying to figure out clrmamepro as we speak. Can someone please guide me to a tutorial or any info how I can control which version of a game I want within the rom. I've also looked in the merging and expanding tutorial, didn't help my situation
