Date: Wed, 26 Jan 2005 13:37:09 GMT From: Peter Naulls Subject: RISC OS SDL Patches Sam, I've attached a diff of the latest changes to libSDL for RISC OS support. These changes are by Alan Buckley and myself. The most significant of these are: Optimised assembler blit rountines - I've attached the file src/video/riscos/SDL_riscosASM.s which is needed for this. Move to using /dev/dsp instead of its own audio implementation. This means that src/audio/riscos/SDL_drenderer.c should be removed Typo fixes. Mainly correct spelling of "RISC OS", but some from elsewhere too.
