Basically, 3 things...
I re-ORGed it from 0x1000 to 0xf000 (which changed the absolute
addresses). I also changed VCS.H so that all the read ports from
the TIA went from from 0x to it's image at 3x, which must have
been the convention (non-overlapping equates for read & write).
Doing these two things makes it "bit-perfect".
Finally, I just changed/added some label names to match Joe's
presentation:
VNCTRL: F032
GSGRCK: F157
LDSTEL: F572
CHKSW: F2DA
COLIS: F444
STPMPL: F214
ROT: F2A9
SCROT: F1F2
VOUT: F054
Not a big deal...but it helped me follow along. I have Joe's
presentation from the last two years at CGEXPO that I can scan in
for those interested.
