Could the Sidekick potentially emulate a full c64 on a vic20?

Would be super cool to plug in a cart and turn a Vic into a c64 or 128. I realise it's not in scope this project, but I'm curious if it's feasible?

This is what you’re looking for: https://youtu.be/twbt9VBtxdk?si=FERRLB_2hFd-lCdr

it‘s a dedicated pcb for bmc64 that uses the c64‘s keyboard and joystick.
output is via the raspberry hdmi

Interesting for sure. I was more hoping for something similar that would leave my VIC20 as it is, but also give me the option to run an emulated C64 while keeping the VIC's keyboard and gameport functional (Hell, since we're emulating, why not shoot for an Amiga as well? :) )

In principle this would not be hard to do: let the RPi run BMC, plus some code on the VIC20 (or other original system) which reads keyboard and gameport(s). It would be more tricky to use, e.g. the serial port as timings/latencies there are more critical.

It would certainly add an extra benefit for VIC20 owners if possible. It's a bit personal for me... Dad bought us a Vic just as all my mates got C64s. In my stupid kid brain I always thought commodore should have made an upgrade cartridge so I too could play ghost busters... Now that it's kinda possible, would be nice to see.
