No it didnt take that long after duplex logo press x then black screen 5 to 15sec then 'The last of us' pulsing at the corner then max 10-20 sec you get a black screen after that the big LAST OF US LOGO then you get the screen for Language options. I am on Rogero 4.3 V 2.5 with MM 4.20.
I had no problems at all. Rebug 4.21.2. Installed to internal due to all the big files.
Run it without disc in the drive and it works fine. Takes AGES to load. Did nothing to it. Duplex version with that stupid duplex load screen.
I patched the eboot myself and it still works with no duplex loadscreen
Eh how you make it to work... I'm on the same cfw as you rebug 4.21.2 using multiman 04.40.00.. I edit the EBOOT.oring.BIN to EBOOT.BIN and delete the Dublex EBOOT.BIN.. Installed to internal ... And all I get r black screen with the last of us logo on bottom right... I waited but dunno I should have waited for how long...
