Plays all Game Boy, Game Boy Color, and Game Boy Advance games out of the box. FPGA hardware just like the Super Nt, Mega Sg and Analogue Nt before it. It also has a built in music sequencer. The screen capability is pretty damn nice.
It will play Neo Geo Pocket (Color), Game Gear, and Lynx via hardware adapters. It will also eventually have a dock available so you can play these games on your TV.
It’s a pretty impressive all-in-one device. $199 will be the price (plus their ridiculous shipping costs presumably… that will make it like $229 in total) and I think it might be worth it. There are two FPGAs inside so you can tinker with the other one (or use stuff tinkered by others).
