The features I like
- Excellent backlit lcd screen (but the screen format is not exactly the same as the original Gameboy Color)
- Separate volume control
- Has a very good battery life
- High compatibility with GB/GBC games
- TheEverdrive GB cartridge is working fine
- It comes with 66 builtin games (although I think the latest revisions don't have these games anymore integrated)
Things I don't like
It has an 3.5mm headphones plug, however it simply does not work. Sound continues to come from the small speaker. This is a shame.
Also, the internal speaker is wired for mono sound output and don't play all the instruments if the game is programmed to play sound in stereo.
It's a very good gameboy color clone.
Screen quality is amazing, compatibility is very high, it has a very good battery life. If you don't need to listen to the audio through the 3.5mm jack, then this is for you !
