Hi everybody,
I have a very lamer question. How does the ROM paging work?
What is the meaning of the lower 4 bits of $FDD0-0xFDDF addresses?
Now I can work on my emulator, but all my documentation is far away and I don't want to wait for weeks when I can go home.
Well...
When I made the Plus4 built-in roms, simply I changed the $8000 and
$C000 areas, they have the same size. Now I want to implement a cartridge support and for example I have an only 8k long ROM file.
Where can I map it and how (I mean $FDDx)?
If anybody can help me with any info, please send me!
Greetings,
Zsolt
