Seconded. I'd like the new MBC1 and MBC2 pages to explain their quirkiness as arising from a limited I/O pin count. I'm willing to write this once we agree in principle on what to include.

"First you lend them your money, and then they hold on to it for you..."

I'd say that the concept of banking as instant-load overlays is worth explaining by itself, in a separate page — as it applies to any mapper, not just licensed ones. The characteristics of the MBCs can probably be summarized in a single page after that.

there was a bit of a discussion on discord and if im not mistaken it concluded that we should explain banking separately somewhere around memory map, since gbc features bankswitching
