| Short Description | Sets the "SRAM page"(?) used by Layer 2 for video memory. |
Bits 5-0 store the number of the "SRAM page" used for the standard Layer 2 screen. The default is 8.
It is not clear what an "SRAM page" actually is. It does not correspond to a "bank" in standard memory management because Layer 2 is too big to fit into a single bank (it is $BFFF big while a regular bank is $3FFF).
