Ideas to shop around
Directions rather than one particular thing, for when you’d rather choose. Some come with a few that fit.

Retro handhelds
Which handheld? Anbernic RG35XX and Miyoo Mini are small, simple Linux handhelds that play 8-bit to PS1-era games well and are very cheap. The Retroid Pocket 5 and the newer Pocket 6 run Android, so they handle PSP, Dreamcast and many PS2 and GameCube games and can also run mobile games; the Pocket 6 is the faster of the two. For Nintendo DS and 3DS games, which use two screens, look at the dual screen Retroid Pocket Duo or the more powerful AYN Thor. The Analogue Pocket is different: it uses hardware reproduction to play real Game Boy, GBC and GBA cartridges, so it suits people with a cartridge collection.
