Greetings to all of you.This is my first post on these fora,and i hope i can use your technical knowledge on the subject.
Before 2 years i bought a ultimate mortal kombat 3 jamma pcb.For all intends and purposes the board seems legit and original midway board.It also plays well except from a bios error that you can see in the photos.
Instead of a regular security chip,this board has in place a different one that seems user made.It has an unknown IC (unknown by me and different from the regular i see on the internet) combined with a resistor.
The question is : Did someone broke the protection ic code and reverse engineered it?And if so why?
The rest of the board is original,as far as i know the only purpose this can serve is if it was a different game and converted to UMK3 and they didnt have the security chip.But the roms and the stickers on the roms seem right.
Below are the images on a google photos folder.
