This patch allows you to have a 128x128 image as the Nintendo Presents logo, with an optional feature to allow a custom palette to be loaded as well. Check out the asm file for more info. Included sample ExGFX and mw3 files for the image you see here.
Being able to insert 128x128 images allows much more impressive "Nintendo present"-screens.
Of course it "only" covers 50% of the screen, but it's 1000 times more user-friendly than any other existing patch on this site.
I can highly recommend this one!
