- added missing *BI2 = 0x817E5480; to Disc_SetLowMem() for wii games. - added missing memcpy((void*)0x80001800, (void*)Disc_ID, 8); needed for debugger and ocarina cheats engine. - fixed default setting for savegame emulation back to OFF (0). v5.5.0 and v5.5.1 new clean install's would set it to FULL (2) which caused wii games to crash on boot up. if you have this issue you can simply go to main settings>nand emulation settings and set it to OFF. - changes to STexture::fromPNG() to hopefully clear up the out of mem issue when downloading and converting the cover png to a wfc cache file. - v5.5.2
