I think the Sony Solicitors will love this one?
This is the Double Match Game handheld and it's made by somebody or other in China.
As you can see it's remarkably like the PSP. Right down to the box artwork.
It's a very impressive piece of kit. Comes with 5 built in games and mine arrived with a Multi-Cart containing 112 extra. All games are the usual NES/Famicom ones or hacks of the same. There is a pretty good selection and the Multi-Cart doesn't appear to have the usual set of games repeated over and over. I've only checked about 30 but so far so good. Carts are the same size and shape of GBA cartridges and One Station Carts also work fine.
It takes 4 AAA batteries but 9v mains adaptors are also supported.
Comes with English Manual, AV cables and a second handset. TV out and two player games are supported. TV out is fine.
Buttons are laid out exactly like those of the PSP and are acceptably responsive. The screen is smaller but is bright and clear. It is , as you would expect, a lot lighter than the PSP.
The only problem I've had is that one of the battery covers won't stay on when batteries are in place but that's a minor quibble.
Excellent stuff from those good people over at http://www.dealextreme.com/. Cost was about £20.
