When usiing Regen debugger, I can set breakpoints on VRAM access in adresses 00000 to 2FFFF.

2FFFF ? What is there after 0xFFFF ?

Hi,

the MD's VRAM has 64KB:

0..FFFF which is 0..65534 or 64KB.
I think it mirrors but I would have to look at the memory-map to check. Have a look in the Sega2F document.

Cheers,

Minty.
