[Gmecm] Adjusting 7730/$8D for larger cam

[Bill Shaw]

Hi Clair,

Congrats on getting it running.  I save into a new file every time I 
save,  keeping a copy of every one I burn,  as well as a text file 
describing each and every single change in each version.  I'm up to 
mybbzb69.bin at the moment,  will probably go through a bunch more with 
the new engine.  Disk space is cheap.
