rofl0r 7169db1e62 PSP: don't block on joystick event query 
using the blocking sceCtrlReadBufferPositive() effectively turns SDL_PollEvent() into WaitForVblank(), because the functions does exactly that if no input is buffered.
due to this, calling SDL_PollEvent() once per frame averaged in 7 ms delay out of the available 16ms budget to get a frame calculated and drawn to achieve 60 fps.

Simple DirectMedia Layer (SDL) Version 3.0

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.

Enjoy!
