Building the code

[MickGyver]

I tried building the code in the master branch but am unable to get it working. It builds fine without errors on both Ubuntu 20.04 and Windows using VS Code but after uploading the uf2 to the Pico and installing the Sidkick to the C64, I get nothing, SYS 54333 is not working and there is no sound. Do I need to configure something in the code to get a successful build?
