Different areas of RAM used by some reasons. For example at 0xac area disabled CPU cache, or 0x0c it's a physical address uses for DMA transfers and 0x8c used as default work area.

Thank you swat

at 0xac area disabled CPU cache, or 0x0c it's a physical address uses for DMA transfers and 0x8c used as default work area.

Can you elaborate on this?
I have been troubled by this. Is the address starting with 0xac and the memory address starting with 0x8c the same? Is there just a difference in caching?
such as

0xac010000
0x8c010000
0x0c010000
Are these 3 addresses one? Is there a difference between caching


I found several KATANA games and put them together with other functions, and the assembly seems particularly difficult.

Can you recommend a KATANA game or app about the use of these functions?
