I don't remember Bloodlust releasing patches for specific games, but I think the team behind Dolphin does that. At least, certain revisions seem to work better with certain Wii games than others.
Actually, I'd kill for Sardu (or whoever) to release a new version of Nesticle.

It'd probably have to be recoded from the ground up, but it was always the most emulator to use because of its "view graphics table"
function. You could actually edit the graphics mid-gameplay and save to the ROM
(assuming there was a VROM for the emu to write to)! Sardu was a genius.
