Hi,
In Sprite Mode 2, it is requested to set bits 7~9 to 1 in the VDP register R#5 which manages the location of the Sprite Attribute Table (SAT) in VRAM.
From what I have read (and according to the OpenMSX debugger), in fact, only bit-9 really counts in the calculation of the SAT address.
Changing bits 7 & 8 does not change the SAT address, but changes the colors displayed on the sprites.
Could someone tell me the exact role of these two bits?
I didn't find anything in the V9938 documentation.
