vrEmu6522

6522/65C22 emulator written in standard C99 with no external dependencies.

Initially created for my HBC-56 (6502 on a backplane) Emulator

Development status

Unlike my vrEmu6502 and vrEmuTms9918 libraries, this library is in the very early stages of development. So far, I am only implementing features of the 65C22 that I am actively using in my HBC-56 project.

Supported features

  • Timer 1 (one-shot and free-running modes)
  • Timer 2 (one-shot mode)

Unsupported features

  • Everything else

Additional features will be added as required.
