This is a long shot,
But maybe someone here will have some experience with this. The SVN has a zlib library that has been ported to the PSP. There is also a zziplib library. I believe that zziplib allows you to extract files from a zip and store them straight into memory.
Does anyone have any experience with either of these libs? My goal is to take all of my images and store them in a big zip file to save space. I would then like to use the aforementioned libraries to extract individual files from that compressed zip and load them into my game. SDL has interfaces to zziplib if I am not mistaken, which may even make loading images from a zipped file easier.
Writing the source code for a game is hard enough. I donít have the time at the moment to look into how these libs work. If anyone has any experience with them, please share it. I am sure it would be extremely useful to anyone developing a game with significant graphics.
