Revision 1.8 02/21/2006 01:04:15 mitu modified am.h path. Revision 1.7 02/20/2006 04:13:07 mitu changed include path from dolphin/ to revolution/. Revision 1.6 02/02/2006 07:26:59 aka Modified using MEM functions instead of OSAlloc()/OSFree(). Revision 1.5 02/01/2006 08:07:50 aka Added #ifndef(#ifdef) HOLLYWOOD_REV - #else - #endif. Revision 1.4 2006/01/31 08:07:05 aka Added cast from u32 to u8* in relation to changing API around ARAM. Revision 1.3 2006/01/27 04:54:59 ekwon Corrected "\%" escape sequence warning (replaced with "%%"). Revision 1.2 11/08/2005 02:55:02 aka Changed suiting to Revolution's audio spec. Revision 1.1 11/04/2005 05:01:39 aka Imported from dolphin tree. 2 4/30/02 4:43p Eugene Fixed pad read contention between UI and application.
