Selling my childhood - Advice

Hi! Looking for some advice on whether I’ll be able to sell these items. I’m new here so not sure if this is against the rules…

Games - the ones on the left side of the image Pokémon Blue etc don’t seem to work in my Gameboy SP. The right hand side games, leaf green etc all work.

My gameboy advanced sp works but I can’t find the charger. Crazy that I haven’t turned it on in 15+ years but it still has charge.

Gameboy pocket I don’t think works but I’ll need to get some batteries to check.

I’ve looked online and seen rough price guidelines but unsure if I can sell games that aren’t working on my end?

Appreciate the help in (gameboy) advanced!
