Just a question (may be a bit out of the subject) : does the ARM can emulate the FM synthesiser ? If it can, there is no pbm of transfering big sound waves thru slow memory band because the ARM will direct create them in his own memory. To slow down emulation, the main CPU core will just spacing the...

Re: Kos And Pngs Layering

Hi, I wrote a little 'SDL like' lib that use the KOS/Pvr. This is very minimal and I use it for my project. With It, you can create a pseudo surface based on a KOS Texture and blit it directly on the screen (no buffers or any surface blit to another). You can use filters, zooms, offsets (for color t...
