Trying to Dump Metal Storm from Retrobit

Post by mistermorcus » Sun Jan 19, 2020 9:09 am

I've been doing some research and trying to find out if it is possible to dump Metal Storm from Retrobit. I have seen it mentioned that it is using mapper 268 and is a variant of the Coolboy/Mindkids board. I found a pretty good writeup of it here:

There is a photo of the pcb there, but I can take some more shots of mine that are a little clearer. I also found some more info in this thread where copynes scripts were converted to anago scripts, but since it was for a different rom I was not sure if it would work:

Unfortunately I don't know much about the scripts required for something like this. Some people have said that the kazzo can't maintain the proper m2 signal but in the other thread I referenced it seemed like if I start scanning at a certain location it would prevent the reset lockout. I appreciate any help that can be offered.

Mapper 268 is quite a clone of MMC3 with some extra:
