MVS->AES conversion issues

So I've been tasked with finishing a Prehistoric Isle 2 conversion, but I'm having some issues getting it running. I've swapped all the chips over and the game boots, but has garbled graphics. It seems to work just fine apart from the graphics issues. I've checked all the jumpers on the PROGBK1 board and they're the same on the original and donor boards. I've uploaded a video of the issue here: https://www.youtube.com/watch?v=9DcRjux1b1k
Also a picture of the board here:

Not sure where to go next with diagnosing the issue, does anyone have experience with these?

Looks like the CMC is fucked.

Did you make sure to use the same revision NEO-CMC? 90G06CF7042 or 90G06CF7050

I've seen that problem many times, here's a sure fire fix:

1. Take a shit on the boards and spread it evenly.
2. Close up the cart, attach a nice looking label.
3. Print out a nice insert and stuff it in the case.
4. Wrap it up in a Family Dollar bag and throw it in a box.
4. Ship it to France.

Looks like this is going to be the issue, the previous person used a KOF2001. Hopefully he's still got the old roms kicking around so we can put it back together. Thanks for the help <3

KOF2001 is a CMC50, you need a CMC42.
