After many try, i give-up... I cannot start a game from a channel that require the ios223 from the FAT32 partition.
All my game start, i mean ALL my game start from config ubs loader and GX, even the game require the ios223 (Guitar hero, rock Band, etc.).
Game's from channel start but NOT the one that require the ios223.
I've try many parameter, i've done many search on google and here, but without good result. All I get is a black screen after i've start the channel.
I've reformat my drive to WBFS and i will wait a little bit longer.
But keep the good work!
