To be specific, the Pocket works with Game Boy, Game Boy Color and Game Boy Advance cartridges right out of the box. And with the help of an adapter, you can also plug in cartridges for game Gear, Neo Geo Pocket Color and Atari Lynx as well.
Analogue says that the pocket is made using two filed-programmable gate arrays (FPGA). This means its innards are engineered to mimic the original gaming devices, so there’s no emulation going on there. Its 3.5-inch display also comes with a resolution of 1600 x 1440, which is double that of the original Game Boy. It’s also not just a video game device. It comes with a digital audio synthesizer and sequencer called Nanoloop. Which is fitting because, according to Engadget, Nanoloop only ran of official Nintendo hardware until recently.
And finally, the Pocket is also compatible with the Analogue Dock, which allows you to output the Pocket onto a TV via HDMI. You can also use the Dock to connect Bluetooth controllers. The Analogue Pocket will come with a US$199 (~RM834) price tag, and will be shipping in 2020. It looks like the company has not decided on a price for the Dock just yet. No word on the price of the adapter, or if it will be available alongside the Pocket. (Source: Analogue via Engadget)
