Having done a few other Namco System 1 games, it makes sense to do another one using the same technique.
As with Splatter House I don't have a board set running this game so the patches have been tested in Mame but should work 100% on the real boards.
The patch requires no hardware changes, just 2 eproms patched and reprogrammed.
It is also compatible with the FIX version (MM1_P7.BIN) rom that removes the need for the custom 151 chip.
To reset the High Scores just power up the board with with dip switch 7 turned on.
I have a request now, if you apply this patch and it works please either click the Thanks option for the post or add a reply so other people can see it works.
