Memory management (banking) in the C128 is unlike the C64 or other 8-bit Commodores, since it uses the MMU to switch blocks of ROM and RAM in and out of service. This can seem kind of complicated at first, but it’s essential to taking full advantage of the resources that the C128 provides, so I thought I’d do a whiteboard tutorial on how banking works and how to do it in assembly.

Looks like I still need to work on lighting. I added a lamp, but there are still some shadows. I hope that doesn’t make it too hard to read my handwriting.
