I just wanted to chip in and say you’re doing an amazing thing!
No matter what the quality or resolution these are going to be so special.
We still watch DVDs on 4k tvs - and that’s something like 480p (or maybe 5 something - I don’t know).
Big love to you 🥰🥰
The bit that makes this tricky is that it’s all tied to an email ID.
Not as simple as selling some hardware or a game cart - you can’t wipe it as the activation servers won’t recognise it, so it’s ‘stuck’ with an Apple ID that’s probably tied to loads of other stuff.
