If you've managed to get some emulators up and running on the Nokia N900 and missed something while playing Super Mario or other games, there is a cool piece of hardware which is a must have for every qwerty - smartphone user and games enthusiasts: Game Gripper.

Game Gripper: is an accessory for your smartphone that clicks on your hardware keyboard and allows you to enjoy games & emulators with a controller. 

Every game & emulator that allows custom keyboard bindings is compatible

basicly it's a cover for your keyboard with buttons in the right position for hitting the right buttons on your keypad and giving you a gameboy-ish feeling, when you play some jump&run or arcade games.

the Game Gripper is available for some Android phones like the Droid (Milestone) or Morotola Backflip and now it's available for the Nokia N900, too :-)
