Hi B!

I´ve been looking at your rom, it looks good so far. It has a great tie
fighter, by the way.

One thing that I´ve noticed is this:

   10BC  AD9602              LDA TIM64T
   10BF   D0FB                 BNE $10BC

Are you really trying to read TIM64T or it was just a mistake? Either way, I
would like to know what would happen with this read on a real VCS, because
PCAE doesn´t seem to care and returns the timer value.

And since we are in the subject, which PIA registers are accessed with the
addresses 283,29D,29E and 2A2?
