update 20130917: mail from Charles McDonald:
Another one! It feels like Christmas now.

This is nearly identical to Kevin's set, even the same NOP patches,
other than the external memory at D000-FFFF which shouldn't be
factored in. That memory is completely different since they dumped the
running game at a different point in time. Only 0000-CFFF corresponds
to the original game data, but the bootleggers in each case were lazy
and dumped all 64K like with other bootlegs.

The only differences to the game program/data area are:

119B -> LD A,2 changed to LD A,5
192C -> LD A,2 changed to LD A,5
4000/8000/8020 : Small changes in data

It's hard to say if these are real changes or just bad bits because
the values differ by a few bits in most cases.

Either these dumps (yours and Kevin's) are from the same version of
the game, and one (which one?) has a few bad bits which was the fault
of the bootleggers. Or, one is a very slight change to the other.

I have the feeling given the volatile nature of the RAM in the
original game modules, there will be a lot of bootlegs with a small
number of changes like this. Just a few bits here and there that are

The daughterboard on your set is really cool, they went to some
trouble to recreate the hardware inside the original module.
