I figured this was something a lot of people would probably want so I made the code as unobtrusive as feasible. It should work on just about any hack, and if it doesn't work on yours you're probably smart enough to figure out what's wrong.

All this does is make the intro text speed up if you're holding a button. It also speeds up fade-out from the movies - this was necessary actually to avoid some rather nasty glitches.
The patch is for unheadered, unsurprisingly. Source code written for xkas is also attached if you want it.
There's still 2 minor graphical quirks with the patch. One is that the SR388 scene may be slightly misaligned, and another is that the palettes might only finish transitioning 31/32nds of the way so they're a tiiiiiny shade off of 'finished' (just about unnoticable). I decided they're minor enough and I'm not going to fix them.
