This patch allows to enable a resolution increase of the game indentified by No-Intro as: 
Mr. Nutz (Europe)

As stated on many places, Mr. Nutz normally plays in a resolution of 256x224. However, a hidden screen setting is locked behind a hardcoded password, @impo@, that exists in the game's code, but it cannot be activated as the @ character cannot be entered in the game's password system. This patch change the password to EXTEND.

If entered correctly, "PICI PICI GO!!" will appear on the title screen, and the game's resolution will increase to 320x224. Note that if the game is allowed to reset to the Sega logo, the resolution will be reset and the password will need to be entered again.
