So here I am again with more 4kb sector issues. For more info on the topic you can read here: http://gbatemp.net/topic/311976-can-we-please-get-universal-sector-size-support/page__p__3943497#entry3943497 Some less useful sources but related to this issue here: http://www.wiimc.org/forum/viewforum.php?f=6 http://www.wiimc.org/forum/viewtopic.php?f=6&t=1475 Now libext2fs supports 4kb sector drives, so does libntfs. But it seems fat32 does not support 4kb sector drives. If I am correct this must be a problem in libogc. Because the libogc devs are the creator of fat32 implementation in the Wii correct? So to make it simple my two questions are: Does WiiMC support 4kb cluster drives? What is the best way to contact the devs of libogc to fix this bug?
