A few blows and it’s working, despite the screen having fallen off (it’s just resting on top now)
It should be easy to glue the screen and prevent it from falling out.
Some people are using combination of superglue and baking soda for repairing all broken plastic parts, if something is broken inside that holds the screen.
I'm curious though to what extent you can make it. Can you have it with the games? Like with the cartridges? I can't find my old GameBoy but I have some of the old cartridges.
From what I heard this should be possible to do it, but let's wait and see when developers release the code.
As someone who recently purchased and tried one of those classic handheld Tetris game consoles in a public market, I can guarantee you such things will always attract some attention [mostly from the older generations, but still...].
Maybe from younger generations also... did you notice how retro things are getting more and more popular again (shoes, cneakers, clothes, etc.)?
I think many things made in past had much more quality than things made today, and everything lasted longer, maybe that is one of the reasons for this trend.
