But I've done this game on mmc3 with additional logic.
Can you tell us what logic you added. If possible with a picture?

I described my modification of mmc3 board in this post viewtopic.php?f=2&t=12421&start=15#p247101

You should use deprotected ROM (you need to apply patch that I posted in this thread earlier)

I don't have clear final picture.

Thank you, I wasn't sure if there was anything else you did. This might be a nice little project for me. I only need to find a good donor that won't be missed.
