[A83] Re: Symbolic's functions in asm
Of course, I assumed he'd know to do that...Also, you probably want to save
and restore the ROM page that was in 4000-7FFFh before you map Symbolic
in...If he is using Symbolic from another flash app, he'd have to write a
loader and copy it to RAM, otherwise for a RAM program just lookup
Symbolic's page, swap it in, call the routine, then swap the old page back
in.
