Joystick Tester for GUI64

[u/GPtechACC]

I've tried to recreate those basic hardware joystick testers that have been around for decades and this one runs on GUI64.

Fked screenshot, but trust me... it runs

- Two square panels, port 1 and 2, CX-40 style: fire top left.

- Both ports monitored at the same time (reads the CIA registers at $DC00/$DC01)

- On a THEC64 Maxi you can live-swap ports 1 and 2 with the controller-swap keys and watch the state flip between boxes

- It's not much and but I've put it here: github.com/gpowerf/JoystickTester64

It's deliberately simple: it just polls the joystick and the virtual LEDs light up.

Question for the crowd: anything else you'd find useful for this?

PS: And when your joystick is in port 2 the mouse arrow does move! Nothing I can do about that :) That's how GUI64 works...

second and third button would be nice :-)

I'll do some reading on that.

The only multi-button setups I've used on the C64 have the second button configured as up, this is for platform games.

The traditional setup is two registers.

5 bits: four for directions and one for fire.

I don't know what happens with a second or third button!

But happy to look into it.

second and third button issn't directly a button, POT-X and POT-Y are used und pulled high. that's an extra read per button. Vice can emulate that, Joyride can test it and is open sorce, so you can have a look :)

Cool! Thanks.
