* Fixed bug in http.c (where realloc *might* choose another address, thanks Dr. Clipper) * Added support to /wbfs/Game Title [GAMEID].wbfs files (thanks oggzee) * Fixed bug in cfg_cleanup when switching partitions * Added BGM class again (for playing background music, requested by dimok) * Added settings for background music again * Fixed bug in MEM2 class (returning an invalid handle when no memory could be allocated, thanks to dimok) * Updated DIP module to OpenDIP (report bugs with this one if you've found them, but report them here: http://github.com/spacemanspiff/odip-plugin) * Added initial code for cios 222 rev5 (THIS DOES NOT WORK YET! DON'T FILE BUGS ON THIS ONE!) * Added fatffs module by Hermes and Waninkoko (THIS DOES NOT WORK YET! DON'T FILE BUGS ON THIS ONE!) * Fixed bug in Settings, which resulted in a crash when the partition was changed. * Added caching for gamelist entries, so switching between different screens/sort options/display modes should be faster * Changed defines in ehc_module, in order to prevent clashes with new defines in rev5
