.fixed I/O access issues with devkitpro r18
.updated OGG support (compatibility with last libtremor + threading fixes from Tantric) .improved controller auto-detection .added experimental support for cartridge hot swapping, check System Options Menu .improved reset (soft/hard) emulation accuracy BEFORE COMPILING, REMOVE THE FOLLOWING FILES: *from ($DEVKITPRO)/libogc/lib/cube & /wii ----------------------------------------- libpng.a libtremor.a *from ($DEVKITPRO)/libogc/include --------------------------------- /tremor png.h pngconf.h DOWNLOAD & INSTALL THE FOLLOWING PORTLIBS in ($DEVKITPRO)/portlibs/ppc (PPC versions, from http://sourceforge.net/projects/devkitpro/files/) *libpng *libtremor
