Aside from your english and from the fact that you're basically doing an app request (that is not appreciated that much here) i can't see the usefulness of your request. Be kind and understand that this is a developer forum.

If i remember correctly, 2 power limitation only occurs on x on PSP, so you can upload a texture of 512x272. alternatively you can: 1) use compressed texture format 2) use downsampled images for textures (i.e. 512*256) and stretch at draw time 2) use less than 4 bytes for pixel (i.e. something diffe...

I admit i haven't read all the thread, but your last post remembers me we are in a cooperative multithreading environment on PSP...in a first approximation this means no thread can be interrupted but every thread must yield issuing a sleep.

MinGW is not an emulator but a framework to let gcc (the compiler on wich pspsdk is heavily based) be suitable under windows (now you can use Heimdall's). We meant a PSP emulator, and even if you had a working one (it doesn't exist a full working PSP emulator) chanches are small that it comes ready ...

No, seriouly: do you need to rotate a texture only to show it rotated on the screen or you need to have the buffer with a rotated image back (e.g. to save it back on disk)?? The former is pretty straightforward:one simple way to do it implies writing a couple of polygons after having setted a rotati...

The word delegate has been introduced by microsoft with their C# to mean a function pointer in a managed environment.

"drawing" means basically copying (or "blitting") images into the region of memory marked as video memory. If -for instance - graphic mode of PSP is setted in a 8888 mode, then each pixel will be rapresented by four bytes (let's say RGBA). To draw an image at (x, y) you'll need t...
