CheatCodes.com has all the official Silent Hill: Origins PSP cheats to unlock everything. If you know of any that we don't have, please let us know.
All published and official codes as of Sunday May 26, 2013 for Silent Hill: Origins are shown below.
To acquire the Plastic Heart for the doll, go to room 204 in alchemilla hospital. You'll find an ice box containing the heart. You'll only be able to access that room in NIGHTMARE mode. Once in the room, go and stand near the box then press x to engage. The CODE is 312319.
The code for the cash register in ANDY'S BOOKS is 213.
Go to the T. B WARD and stand near the control panel of the IRON LUNG. Press x to operate it. You'll see five pressure gauges on the panel. Under each gauge, is a button making five buttons in all. Counting from the left, you'll not need the second and the fourth buttons. I REPEAT: DO NOT TOUCH THE SECOND AND THE FOURTH BUTTONS. Now starting from the left, press the THIRD button once, the FIFTH button once, then the FIRST button once. Again press the THIRD button once, the FIFTH button once and finally, the FIRST button. If you do exactly like I said, the machine will spit out the BASEMENT KEY.
You will find the target pistol in a chair inside WEST SOLARIUM in the sanitarium.
When you access the Cedar Grove Sanitarium, look for the door with the sign EAST SOLARIUM written on the wall beside it and enter then look to your right. The Sanitarium map is lying on the table. Pick it up.
To acquire the golden egg in alchemilla hospital, go to room 202 in nightmare mode. You need that egg to gain access into the ladies washroom downstairs. Before using the mirror in that room to trigger NORMAL mode, go first to the rusty flashing toilet and retrieve the Plastic Liver from the cistern. Now go to the mirror and trigger normal mode where everything around Travis returns to normal. Go back again to the toilet and collect the Staff Loung Key. Now go to the Staff Loung and collect the Exam Room Key.
I'm sure you have the alchemilla hospital Exam Room Key by now. If you have it, you'll find the last two Plastic organs in the Exam room. Also there is an anatomy doll lying there. Stand near it and press x to engage. You will get the glass eyes from this doll but listen carefully and follow this process: Place in the HEART first followed by the LUNGS, then the INTESTINES, followed by the STOMACH and finally the LIVER. The doll's eyes will open automatically. Stand near it's head and press x to collect the Glass Eyes.
At the beginning of the game, Travis must go to ALCHEMILLA HOSPITAL to visit the girl he saved from the fire. Press the triangle button to view the map of SILENT HILL. You'll see various locations indicated by their names on the map. Go to the POST OFFICE, climb the stairs and pick up the Room 502 key on the floor of the stairs in front of the door. You can use that key later at the Motel.
NOTE:There are nine HIGHLY important items which needed to be collected to successfully complete
ALCHEMILLA HOSPITAL. They are the following:
1)Plastic Lung (2)Plastic Liver (3)Plastic Heart (4)Plastic Stomach (5)Plastic Intestine (6)Staff Loung Key (7)Exam Room Key (8)Golden Egg and (9)Glass Eyes.
Once inside Alchemilla Hospital, use the elevator to get to the 2nd floor. Go to room 205 and retrieve the Preliminary Diagnosis Note on the trolley then attempt to exit. After THE ingame movie, stand in front of the mirror and press x to trigger what I call the NIGHTMARE mode. Everything around Travis will become old, rusty, dark and dangerous. There will be a box with a plastic lung in it. Pick it up.
Exit alchemilla hospital and take a look at you map. Look for BUTCHERS. Go arond TOWN HALL and take CIELO Ave then LOW St to BUTCHERS. Exit BUTCHERS through the back door and use TOLUCA Ave to get to CEDAR GROVE SANITARIUM.
To face the area boss of alchemilla hospital, go to the female washroom after you have acquired the Glass Eyes. Use the mirror to trigger NIGHTMARE mode then go back and stand in front of the Exam Room. Press SELECT and choose Glass Eyes from you items then select USE to fix the Eyes in the DEATH MASK on the door to unlock it. Enter and go into the DOCTER'S OFFICE to face your FOE.
