Silent Hill: Book of Memories Cheats - PS Vita

Konami Code
At the starting screen main menu (Your Character's Bedroom) enter the Konami Code ([Up], [Up], [Down], [Down], [Left], [Right], [Left], [Right], [Square], [Triangle], [Start]) to get a free Robbie Doll weapon as well as enable the sale of Robbie Dolls at the shop. You'll know the code worked if you hear a child's laughter. You need to input the code each time you load up your character. If you reload your character, you can re-use the Konami Code to continuously get more free Robbie Dolls.

Red Piramid's Kart Jam 3,000 Title Screen
At the title screen, wait until the tv is centered on your screen, and press [Start]. A loud announcer will yell the title of the videogame displayed on the tv. Obviously a reference to the famous Pyramid Head.

Glitch: Howard's Shop Accessories
This glitch allows you to get your Memory Residue (MR) back that you used to buy an ACCESSORIES (works on accessories ONLY). First you need to have enough MR to buy an Accessory, after that SAVE your game, then go to where the shop is and buy an ACCESSORY. After buying find an area with enemies or traps and let your character DIE, then retry the zone. Now you will notice that you have all your MR back just before buying the accessories. Quit the game and go to Character Options and check your Accessories there you will see that you have the accessories you just bought from the shop but got your MR back.
