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

[Clair Davis]

Well, I guess that's what I'll do, just start with XXX001.bin or something
equally random, just so long as there's some sort of sequence.  Keeping a
text file with the same name will let me keep just one XDF and still have
all the changes I've made and when.
