just about a week back i had got my hands on the critically acclaimed (atleast for gamecube & ps2) Resident Evil 4. Excited, i installed it just to find out that the game had NO MOUSE SUPPORT, crappy gfx & PATHETIC keyboard controls!
THE GAME WAS UNPLAYABLE!!!
Today, i googled ,just to find some patches, which can make the game enjoyable...
MOUSE SUPPORT MOD :
Add mouse support to the game! yipee!!!

(but not to the menus though

)
dont expect the mouse to behave like a generic fps mouse(like Quake 4, UT).....but its atleast better than those keyboard controls
PATCH v 1.1
BEFORE
AFTER
- General adustments and improvements made to graphics, lighting, and effects.
- Rare issue causing the game to freeze when skipping cut scenes addressed.
-The above fixes are fully compatible with save data from version 1.0.0
Hope this Helps
