Low Res, High Res, Double High Res use main bank and aux bank and Super
Res uses $E0 bank and $E1 bank. My question is which memory location Second
Sight's modes such as 640x400x256, 1024x768x256, and beyond are stored.
Someone told me that all pixel information are stored in Second Sight card's
RAM, but they do not store in the motherboard's RAM.
If pixel information is stored in Second Sight card's RAM, how can 65816
instructions access by modifying pixel data in the memory location that they
should be in motherboard's RAM. Is there a special softswitch to transfer
pixel data from motherboard's RAM to Second Sight card's RAM?
I am not sure if the information is wrong. Please let me know when you
find the information where pixel information is stored. Thanks...
