ps2 modchip usb

[royal]

I recently got this modchip, but am unsure on how to install it on a Japanese system. Does anyone have the instructions and/or pictures? Also does this modchip allow me to play US games or just backups. Thanks adhead of time. If i cannot find information on the install, would anyone with a US system like to buy this. Works through USB with only one wire to solder and would be cool. Thanks ahead of time.
