Yep folks, it's me again with some more "he doesn't even know that?!?"
questions for y'all... ;-)
I now have the BBC ROMs loaded into my emulator and working okay; I'm
working steadily through the ROM code and so far my 6502 appears to be
working okay. It's slow progress, though...
Anyway, I've got a few questions which have arisen since I started trying
to get the ROMs working.
What is stored at &258? As far as I have got in the emulator, it is
loaded but nothing has been saved in it - does it hold something special
or am I getting things wrong again?
Do I *really* not have to pay attention to Sheila peeks/pokes? I was told
that I just had to start up the emulator with BASIC loaded in at the
paged ROM area (&8000-&BFFF) but is this really true? So far I have come
across addressing of FE4E, FE42, FE40, FE43, FE4F as well as FE30 (the
only one which I know what it does!). Can I really ignore all of these?
