Hey there! So, I recently watched a video from Gaming Historian about the Virtual Game Station [1] and I decided to give it a try. It works very well on Mac OS 9, but I lack a usb controller that's compatible. So, I was thinking about coding my own driver for the PS3 sixaxis controller!

There's this doc on [2] that shows us the headers for drivers, [3] a driver written in assembly for old world Macs and [4] a driver apparently written in lisp?

So, I don't have that much experience with coding on the OS 9, so I was wondering if anyone could provide me some guidance on where to start and how to set up my env.

Thanks!

I don't think you want a device driver for a USB device.
[3] is a DRVR driver for an emulated storage device? DRVR drivers are 68K.
[4] is more disk driver stuff. Just a bunch of low memory globals equates. It's a lisp binding for classic Mac OS API. Like how Apple has headers for 68K assembly, Pascal, and C.

Is the PS3 sixaxis a HID class USB device? Test that by connecting it to a Mac. Use USB Prober.app to dump info about the device. It will list interfaces of the USB device. If the USB device supports HID, then it will also have a HID descriptor. There's versions of USB Prober that work with Tiger to Monterey and probably beyond.

What does Virtual Game Station require for an input device? I think HID should be sufficient, unless they chose proprietary devices. Does it support any ADB devices? ADB devices are not HID. I suppose one could make a HID driver for an ADB device - I've done that for Mac OS X - not sure if that's possible for Mac OS 9.

There's a USB DDK for Mac OS 9 (1.5.5f1, 1.5.9f1). It also contains a classic version of USB Prober.

Since Virtual Game Station is PowerPC only, and USB doesn't exist for 68K Macs, you probably want your driver to be PowerPC also.

I might be wrong or I might be crazy, but I think the DualSense (PS5 controller) have an HID descriptor?

Same, I don't think it needs any proprietary drivers.

This is... unexpected. The PS5 controller works on Mac OS 9!!!! LOL

At least it shows up on USB Overdrive, not working on VGS... yet.

after it´ll work with your games, pls use it in some other apps of our choice and let us know.
