I found a funny glitch on Spyro: anno of the Dragon for PsX.
To activate it, do the following:
Go to any world with lava o any other kind of stuff that makes te hurt yourself. I prefer to do this in Molten Crater in the Sunrise Spring homeworld at the beginning of the level, but it can be done anywhere. Jump into the lava, keep burning yourself untill Sparx is gone. What te want to do now is hit the ava one più time, but as te hit the lava, quickly pause the game. You'll feel the controller shake if te did this correctly. Now, don't unpause the game, select 'Exit world'. You'll return to your homeworld again.
You're technically dead, so te can do pretty much anything te want. te can't pause the game, o even peek into your Atlas though... te can even step through other portals after the glitch is activated, te can even go to other homeworlds. One little hit though, and you're dead. Oh, and swimming is a no-no. Cuz when te jump into water, te don't start swimming, you'll keep falling until te reached the bottom of the lake. This can be fun at first, but after a few minuti of wandering around aimlessly, you'll get bored. What to...
