WonderSwan



The Bandai WonderSwan was a competitor to the Game Boy (interestingly, both were created by the same guy) that never made it outside of Japan, and so it doesn't have many games in English. Much of its titles are anime-licensed and RPGs, but it also has a decent number of (import-friendly) fighters, platformers, and action games.

The WonderSwan comes in three versions: the monochrome classic, the Color, and the Crystal. The Color and Crystal run on the same hardware, but the Crystal has a superior TFT screen and shorter battery life. All of them run on a single AA battery, with the following expected life:
 * Classic: 30-40 hours
 * Color: 20 hours
 * Crystal: 12 hours

There are also AC adapter and rechargeable battery pack accessories for those who'd prefer less battery expenditure.
