R36S WonderSwan Games

Japan-only release

Bandai's handheld was designed by the creator of the Game Boy after he left Nintendo. It ran roughly 30 hours on a single AA battery and never left Japan, so much of its library — including Final Fantasy remakes and Gunpey — is unfamiliar outside it.

WonderSwan on Each R36 Model

The chip is the same in every model, so the rating is too. What differs is the screen: 4:3 panels suit most home consoles, the 1:1 square panel suits Game Boy and GBA and shows 4:3 games with bars.
