Is this a pal game? I'm using any fpga genesis and graphics start to mess up after I die a few times when its set to JAP or US but works fine in EU region. https://github.com/MiSTer-devel/Main_MiSTer/wiki

Nope, any region, according to some reports i have it works well on ntsc genesis and megadrives. And on my nstsc grnesis 1 too. Looks like a fpga emulation problem.

They found the issue. I guess the game needs a unique serial number instead of all 0's. It identifies the game by the serial number.

Why not identify a game by "Domestic or International name" from ROM header? Looks more logical and easy. Not sure how i can generate an serial number and not hit another game SN.

Thanks for the serial. They added an exception for your game to use name after your suggestion.

One of the MiSTer FPGA devs found a work-around and asked if you could give the game a unique serial number.

I'm passing along the Dev's comments:
The bus arbitration in our core is not ideal most games don't care, but some do, so this one needs a FIFO tweak to make it behave correctly but to do that, I have to be able to uniquely identify the game, which means the serial has to be meaningful, not all 0's

I discovered this game because of a recently posted MiSTer video on youtube, and play it on MiSTer myself. Glad to contribute a little for projects like this, great game!
