We currently emulate the Amiga 500 keyboard controller, which was
|
||||
also used in later Amiga 2000 keyboards.
|
||||
|
||||
TODO: - Natural keyboard mode doesn't work with shifted characters,
|
||||
they get sent in the wrong order (core bug?)
|
||||
- Move 6500/1 to its own CPU core so that it can be shared with
|
||||
other systems
|
||||
- Add support for more keyboard controllers (pending on them
|
||||
getting dumped)
