1's company, 2's a crowd!

Another lunch break, another bug fixed. I decided to look at the invader shot frequency since I was getting nowhere with the 2-player game issues, and it was yet another endianity issue. The shot frequency is dependent on the MSB of the player's score; having swapped the endianity for all 16-bit values on the 6809, it was looking at the LSB. Bug #11 down.

As far as I can tell, the single player game is now complete and running 100%. So there's just the 2-player game that has issues; I know of one, possibly two different bugs.

Hopefully, an alpha release is imminent!
