Secret Area At Insomniac Museum
[PS2 Cheat by: Mohawk ]
When inside the Indomniac museum, go left until the very end of the building, then turn right until you see a electrolyser puzzle. Solve it to open a nearby door.
Head through it and stay to your right. Jump across the little fence and continue walking until you see a kind of wall blocking you. You are now on the edge of the building.
Do a high-jump and glide on the other side. Continue and turn right for a secret area. To get a better view of the side of the building, turn the camera on the edge of the building before the jump.
You can also go into the pink building and go as high as possible. Launch a Visbomb (guided missle) and head for the left edge of the building and blow the missile with Circle for a clearer view.

Easy Bolts
[PS2 Cheat by: Mohawk ]
Head to the Feltzin System, and when you get there choose Challenge 3: Fight the Ace Thug Ships. When you are in control of your ship, pull out the nuke & fire. If an asteroid is in the way, aim down a little so it will not impact it. Most of the time, all of the fighters will be eliminated. It's an easy 7,000 bolts for each press of a button. Try it! Hope this helps ;)

Insomniac Gallery Without Skill Points
[PS2 Cheat by: Mohawk ]
Head to Silver City & go to the grinding section of the level. Start grinding and keep an eye on the left side of the screen. Eventually you will see a garage type building. At this point, you need to get off of the grinding rails by getting hit by one of the electricity posts.
Now from here, use your glider to go to a large segment of land around the garage. When you get to the segment of land then you go towards the garage. You cannot go through the door so go around the left side of it. Walk forward until you fall through the floor. Then go a little to the right and then jump up. Then you will be in the garage. On one side of the room there will be a portal leading back to your ship, on the other side there will be a portal leading into the Insomniac Museum.

Start Screen Fun
[PS2 Cheat by: Mohawk ]
From the start screen, don't press anything and watch the games that Ratchet plays. After a while you will see him play Jak and Daxter: The Precursor Legacy, Jak II, Sly Cooper, and Ratchet and Clank.

Bolt Multiplier Glitch
1. Head to planet Damosel/Allgon city.
2. Head over to a lamp post when the game starts and hit it. You should get 84 bolts (this is a test).
3. Turn an go into the room with the taxi.
4. Go straight through to where the protopets are chasing the robots.
5. Next use charge boots to quickly get to other side where the ladder is.
6. When you get to the top, kill the 2 guys that appear.
7. This is the most important part:

Use the swing shot to swing to the secondswing shot thing.
Don't land down where the protopets appear--instead, do 180 degree turn in the air and use the swing shot to get back to where you started. This brings
the protopets out of the sewer thing and start the glitch.

8. Once you've landed, turn around a look back at the platform where the protopets are. You want to use mini rocket gun or hover bomb to kill them.
9. Once you've killed them all, use the swing shot to go across and gather all the bolts. Do not go into next room.
10. Now turn around and jump down where those jet things are floating and kill yourself.
11. When you start back at the ship go and hit a lamp post. It should give you 420 bolts as compared to 84 in step #2.
12. After applying glitch there are 3 main areas to rack up bolts.

A. After the swingshot things (stand in a corner with sheepanator)
B. The next is the dome right after (stand in the door way w/ sheepanator)
C. Finally go out of that room and jump the gap (stand right at the edge with sheepanator)
