# vrEmu6522
6522/65C22 emulator written in standard C99 with no external dependencies.
Initially created for my [HBC-56 (6502 on a backplane) Emulator](https://github.com/visrealm/hbc-56)
### Development status
Unlike my [vrEmu6502](https://github.com/visrealm/vrEmu6502) and [vrEmuTms9918](https://github.com/visrealm/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.
