Yes this is really awesome, think of what we can do with all that screen real estate, a keyboard, and 128k ram
The new emulator version you put out works perfect and now that I see it, there is no need for any switch between keyboard, joypads, etc, just get a separate game pad.
I haven't looked at the keyboard drivers closely enough, but it seems to be suppressing key repeats. By default when it starts up, they keyboard should send out an initial key-down even when it gets pressed, and a key-up when it's released, but also a series of key-down events when it is held down for a time(type-matic repeat). So now that I say that I should actually read into the source before posting...I know you can send a host command to the keyboard so it doesn't send key repeats and/or you can also have it not send the key-up(break code) if you want. This is something I was wondering while playing with the demo there, I don't happen to think key repeats are all that useful. But pretty important if you want to use a keyboard in a game also as a controller at times, can a game tell when a key is held down, or only the moment it is struck? If I wanted to use the standard 'W','A','S','D', forward, strafe left, back pedal, strafe right key setup for a raycasting game would it work?
Yeah, it's wired directly, no converter chip. So I guess the keyboard somehow detects based on the pins/voltage or no USB response that it's connected to a PS/2 port and adapts it's protocol. Probably why it takes a couple seconds too before it starts sending keys. Pretty cool then, anybody can make one by just buying that keyboard and an SNES controller on Adafruit and wiring the Attiny inside the SNES female connector (with a healthy dose of epoxy naturally)!
