We had a productive long weekend here at Directional Pad.
A few weeks ago Andy picked up the Nintendo Wii Zapper and was - as we assume many people were - completely dismayed by the fact that it wasn't compatible with Resident Evil 4. The problem stems from the fact that the zapper and all other third-party gun-type attachments for the Wii Remote all depend on either a mechanical switch that presses the B button, or on opening a hole for you to be able to press the B button on your own. That's all fine and well for games like Link's Crossbow Training, but RE4 uses the A button as "shoot" and the B button as "draw weapon".
So, of course, Andy took things into his own hands, got himself a toy electronic gun, and started soldering.
The result was the RE4 Gun, a wonderful ugly mash-up of a toy gun and Wii Remote, which can work just as well for A-Trigger and B-Trigger games.
