Vice Controls, any ideas?

I’m trying to setup my Commodore 64 setup to be as close to the Commodore 64 “Games System” as possible.

For those not familiar, this is the console version of the system released in 1990. It just had a joystick, no keyboard or anything… but was essentially just a C64 in a blank case with a cartridge slot lol

Anyway, the core info file on this has 0 information on controls, and I never had any of these old computer game systems growing up so I’m at a total loss.

Does anyone know the controls, or have any information on controls for the GS version?

If I can just figure out the basics I can take that and apply it to a GS style profile, but I have no idea what to do here lol

(Side Note: Sorry for creating 2 topics on the same core one after another, I just didn’t think they belonged in the same post)
