caleb_chiang SG I managed to get the gameboot working but for cintro, cannot... how huh? my firmware is 3.71m33 and set is slim. Thanks.
FrozernFire SG currently cannot for 3.71 m33 there is another way: http://www.pspmod.com/forums/sony-psp-homebrew/25172-cintro-3-71m33-3-well-almost.html if you use irshell you just set irshell to auto boot and disable the sony startup screen. then set your irshell startup splash image to your pmf file
