Compatibility of examples with Tang Mega Retro Console 138k

I’m seeking clarification on the compatibility of the examples in this repository with the Tang Mega Retro Console 138K, as this is not currently addressed in the documentation. Specifically, I’d like to understand the following:

Do the Retro Console and Tang Mega 138K share the same PIN constraints for the examples provided?
What steps are required to run the examples from this repository on the Tang Mega Retro Console 138K?
How can I enable USB gamepad functionality on the Retro Console? I’m unsure where to begin.
Additional Context
