#ifndef __XWORLD_SYS_H__
#define __XWORLD_SYS_H__
XWorld: some fixes Fixes sound on most platforms, original root cause was bad menu code as well as DMA callbacks taking too long. Worked around with smaller chunk sizes. Permanent fix would include moving mixing out of the callback. Rewrites input with code from rockboy/doom. Cherry-picks a change from Gregory Montoir's `rawgl' to patch the code wheel screen. Finally, adds a motion blur filter on select targets. Change-Id: I8df549c923c5075800c6625c36c8202e53de1d27
