a SMG_us backup disc should work on 3.3/3.4u console. it goes black after loading the game ? probably a bad disc. NERO the suspected SMG disc with DVDcopyDVD, take a 1:1 burn at 2X~4X may 'recover' ur smg. hv fun. :P
jumper on on d2CKey should be set to NTSC-U according to console region, not per game region.
