GuCopyImage src and dest overlap?

When using GuCopyImage(), can the source and destination overlap if the destination's address is greater than the sources? In theory this should work, aslong as there are nospecial checks for an overlap, or something I'm missing. I'm not at a point where it'd be easy for me to test yet, getting ther...

Load strait into vRam or alloc then copy?

I just wrote a really simple run length encoded image format, and I need to know what the best way to read them into the psp are. I could read them into vRam directly, but I'd be setting each pixel one at a time. Would that be slower than reading the entire thing into ram, then doing a copy into the...

I finally got around to taking a good look at that code of yours, Rachael. Why don't you just keep track of free vram with a global, subtract from it on alloc, and add back to it on free? It would allow for the value to be checked without having to traverse the list. Also, you could then add a quick...

Also a vram compaction routine would be nice, if the vram got fragmented too much over time (but this could simply be avoided by good organization of the valloc and vfree calls). I havn't yet written any code that uses graphics yet, but I was thinking about this last night. My idea for dealing with...

Getting started with PSPGL

Ok, I've installed PSPGL, and got the tests to compile, and they run just fine on my psp. I have only a few questions keeping my from going at it now... as I havn't ever used makefiles and such. Dependencies... in all of the examples given, they include glut.h and that's it. If I didn't want to use ...
