So it is just PWM'ing the halt pin - that's a neat trick 😃

But not Agnus, but the official Action Replay also controls Agnus

There’s a deep dive into the Action Replay here - they both trigger using a Level 7 Interrupt, and the rest, we’ll take a read jvaltane.kapsi.fi/amiga/howtocode/actionreplay.html

I wouldn't have exposed wiring directy from the CPU outside the case, some sort of housing would be good for the resister & switch.

It’s only a temporary mod - it’s not like I’ll leave it connected - if I was I’d build a case for it

Cool and simple. I never own an Atari nor a Amiga. Seeing so many videos about them I almost convinced myself to buy one but then I have realized that for me its a train that left the station. Anyway nice video!

7:00 Circuitbending... 9:00 however this does not change the clock-frequency... interesting yeah.

Thought it would just be hijacking the clock signal, like how the GBAccelerator works. But this is kinda more interesting. And perhaps more reliable, as hijacking the clock signal could lead to a desync between the CPU and other components.

Indeed and it’s probably why the rest of the hardware behaved so well with it too. I was expecting it to be messing with the clock signal too

Yes, but this also leads to crashes if you turn her up too high.

This is something that my brother & I could have used back in the day for Test Drive. We wanted to build a steering wheel, instead of using the joystick. We didn't know anything about electronics or have access to the resources to learn anything. But we thought if there was a way to make turning the wheel left or right pulse the left/right joystick input at a variable rate, it might achieve what we wanted. A small turn would result in short pulses and the full turn of the wheel would be like holding the joystick left/right. We made a steering wheel, gas/break pedals, and a makeshift shifter. It just didn't work as well as we hoped.

I looked into that type of circuit after and it’s actually quite a common approach although I’d never seen it before. When I was younger made a steering wheel for lotus although it was very basic and used a home made tilt switch to detect the rotation (was literally a marble wrapped in tin foil moving around in a cardboard tube) kinda worked but not as good as your idea

You can do the same thing on the C64 or any 6502 by applying the same signal to the RDY pin (wait state input). There was a cart that had a 555 timer PWM circuit.
