Timetop GameKing I

GameKing is a series of handheld consoles released by Timetop for the Hong Kong market starting from 2003. The first console of the series, GameKing I (model GM-218) is an 8-bit console similar in design with Game Boy Advance. The console has quite progressive sound system, however the quality of the screen is considered low for that period, since it has a monochromatic (4 shades of gray) LCD screen like Game Boy with resolution only 48x32px.

The games of the console are mostly clones of games that were famous that era and could be played by other consoles (i.e. NES, C64, Atari 2600) with dropped graphics. The same games can be also played by GameKing II, which has a backlit screen. It has 3 built in games: Drifter, a Wonder Boy/Adventure Island clone, 2003, a 1942 clone and Miner or Mine Battle, a Bomberman clone. Except the built in games the console can take cartridges. Some of them are 4 in 1 cartridges, especially the late ones, meaning that one cartridge hold four games. The games are usually numbered in such a way that the more presentable games have bigger number.

Lastly, it uses 2 AAA batteries as a power source.
