That sounds like a great idea! As long as your joystick case has enough room inside to facilitate the reciever (or whatever you call the part that holds the HDD trays), I’d say that’s one of the more slick universal joystick solutions I’ve seen! Yeah, the 40 pin IDE cable will give you about twice as many signals as you could possibly need, which is nice.
As far as the space inside the trays, you will have to cut down some of the pad PCB’s to get them to fit. It’s not as bad as it sounds. It’s more involved than just soldering to the button contacts, like most folks do, but it’s very doable, even for people who aren’t pro’s at soldering.
I’m actually in the middle of writing some tutorials on miniaturized pad hacks, so if you need some help with reducing the size of your controller PCB’s, those write-ups may come in handy. I’ll try and remember to post in this thread as I get them done :karate:
