I hate messing with that darn PSP Slim support, so I keep avoiding working on Kosmodrones at all these days, I'm afraid...
Just lmk if you need help there, shouldn't be too hard to get it working on PSP Slim/3.71.
It runs on 3.71 now apart from the intro video. There is no way I'm ever going to be able to figure out how to fix that on my own. So if you feel like it, a 3.71-friendly version of the video code or some instructions on what I need to do would be very welcome.

There is a new level in the works as well, btw, so hopefully that will be in when we release the Slim-compatible version.
