that the hack is in there multiple times is normal, its for different versions of system menu (pay attention to the hack min & max versions.
however, i hate to see that the issue is still there. i know what is happening but i don't see how it got to that point.
could you please disable the autoboot & return to options in priiloader, enable debug info , and boot this from HBC

in this dol, go to the hacks menu and give me the log.
it -can- load the hacks slower (giving you a black screen for a few seconds), but thats cause its logging A LOT more right now.
while in the hacks menu, check if 'Block Online Updates' is in the list on the bottom.
ive also changed some things in the file loading code, so maybe the issue is fixed now too.
