If by chance you have any problems follow this it works for me. ( Must know how to unpack the 1.03.PKG ) on your computer
step1. Place (NPUB31419) folder into your dev_hdd0/game directory With the first 1.01 unlocked one. ( Minecraft.Afd.NPUB31419.Install.PKG )
Step2.I Place (NPUB31419-Minecraft) into your dev_hdd0/GAMES folder From this tutorial
You must login or register to view this content. ( ONLY THAT ONE LEAVE THE OTHER ALONE )
Step3. Use FTP or Filezilla to replace the EBOOT.BIN in the dev_hdd0/GAMES/NPUB31419-[Minecraft]/PS3_GAME/USRDIR With the one Creepz has provided.
Step4. Change the 1.03 PARAM.SFO Target Ver. to 1.01 and save it over the original 1.03 ( Games Directory )
Step5. Replace the MediaPS3.arc in the Media folder. with the 1.03 version. ( Games Directory )
Do not change the ICON0.png or the PS3LOGO.DAT AT ALL
Your Done.
