Wow - this looks fantastic!
I came across it while trying to find good quality decals for the Donkey Kong Game and Watch - I have one I restored and want to see if I can print off the decals on glossy paper, as the ones on the unit are gone or partially gone.
I'm going to try a screenshot of yours, see if I can edit out the bits I want, and see how they print off - here's some pictures of it that I tweeted: https://twitter.com/deadl0ck_eire/status/1569018382824906756
