[A89] Re: Forgot one question
Thanks, that is what I needed to know. The part about when a2 is restored
puts a whole new twist on things... that I have not thought about; I think
that I might just forget about teos... or start using -ffixed a2 again...
I'll think about it :)
Samuel, just so you know, I came across another way to make sure that the
calc is on the home screen; cmd_disphome(); (rom call $33F), It is the most
efficient method I have found so far.
