    "Got a faulty Pacmania the other week and have now finally got it working but was fed up with the high scores not being saved even though it has a 28C16 for the settings. So I set about adding High Score Saving to the US version. I am listing the patched bytes below which have to be made to the V0 & P7 rom files. This is fully compatible with the 63701 replacement mcu. It is also compatible with the PM-PRG7.FIX rom that removes the need for the custom 151 chip but there are 3 extra bytes to change which then also reinstates the rom checksum routine. /* Updated */ I have revised the patch to now reset the high scores if started up with dip switch 7 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. PN2_V0.bin These bytes should all be FF before you changes them.
