Hi All,
I have written a AppleII Emulator for Palm. I would like to enhance
the speed of emulation. I found that most of Games/Programs use lots
of time to un-nibblized the data from Disk. Is there any reference of
DiskII Controller ? I would like to know is that some routines is
already built in the boot rom or for every games/programs, they needs
to implements un-nibblized rountine ?
Regards,
Hilary
