The other handheld emulators are similarly priced. - https://www.goretroid.com/products/retroid-pocket-5-handheld

Although it isn't mentioned on the box, the Gamestation Go is hiding some bonus features, including emulation of systems like the SNES, Neo Geo Pocket, Dreamcast and N64. Loading a correctly formatted MicroSD card with the supported ROMs allows you to access these "hidden" emulators. While performance is patchy (Dreamcast games lack sound, while N64 emulation is buggy with frequent audio skipping), it's a nice little bonus to have; NGPC games run pretty flawlessly.

I still can't find tech specs on it, like processor, ram, ect.
