I love the famitsu-style Game Boy Pockets. This one with white buttons came out great. It feels awesome. It has the funnyplaying retropixel screen, touch color control, properly functioning dim wheel, new speaker, and a voltage regulator (tested working with an everdrive). I also installed a cool rear-facing LED so you can keep an eye on battery life (my one issue with this style is the lack of LED, so I fixed it on my version by adding a discrete LED that is viewable from the side and back).
If you intend to play your old Game Boy collection or try out your flash cart without the bulk of an original Game Boy, grab your AAAs, this one is for you!
