I think it's been about a year since I got it! At the moment it's not my go-to choice when I play (I did use it quite a bit the first months) but only because these days I'd rather lay on my couch and play on my Pocket, but I didn't face any issues whatsoever.

GBOperator works wonderful, definitely check it out specially if you want to make sure your Pokémon aren't erased once the cartridge's battery dies! Analogue makes the Analogue Pocket, which can be docked (I don't have the dock, but I do have the Analogue Pocket and it's by far my favourite way to play GB/GBC/GBA games.

As someone who didn't own an N64 back in the day, I've been really loving my Analogue 3D!
