| Short Description | [[ShortDesc::Sets the bank number where Layer 2 video memory begins.]] |
Bits 5-0 store the number of the "SRAM page" (ie, bank) used for the standard Layer 2 screen. The default is 8. Because the layer 2 screen is 48k, it actually occupies 3 banks, and the number set here is the first; so by default, it occupies banks 8-10.
