Never mind I got this to work by switching to GU_TRIANGLE_FAN in sceGuDrawArray and providing four vertices instead of two, rotating them manually and setting the texture coordinates as appropriate. Thanks for your help though Raphael.

I had a look through the SDK samples and they seam to use something similar to this but it dose absolutely nothing in my app (the samples all...

2D bitmap/texture hardware rotation?

Hey I have the GU set up for 2d sprites (will provide GU setup/rendering code if it’s needed) but can’t figure out how to have it rotate them. I did write a software implementation but it’s turning out to be far too slow, so is there anyway to have the GU do this? Can anyone point me in the right di...

Aligning memory to 16 bytes with new operator

Hello again, I’m having a bit of trouble with my images looking slightly ‘corrupted’ when displayed on the PSP. I had a look in pspgu.h and noticed this: /** * Set current texturemap * * Textures may reside in main RAM, but it has a huge speed-penalty. Swizzle textures * to get maximum speed. * * @n...

new and delete are not valid C operators. They only work in C++. Be sure your file is named .cpp, and not .c.
It is named .cpp. PSPSDK seams to require “extern "C" { … }“ for C++. Tried removing it with no luck either.

Hey, I’m not new to programming but have recently been learning C/C++, reading books and looking over sample PSP code. I’ve managed to get quite a few things to compile and run on my PSP but there are a few things still confusing me: From: pspdisplay.h /** * Display set framebuf * * @param topaddr -...
