Please more details. Is this image hand crafted? If not, how has it been created? Is is supposed to work? From a quick look it seems as the root directory is bad but we report progress in ->iterate. ctx->pos is 2, we set it back to 0, because of the faked dot entries. but fat_get_entry() did not make any progress and we report 0 back to VFS. So, VFS sees progress and the game continues. Does the attached patch help? -- Thanks, //richard
