I found a funny glitch on Spyro: año 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 tu 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 tu want to do now is hit the ava one más time, but as tu hit the lava, quickly pause the game. You'll feel the controller shake if tu did this correctly. Now, don't unpause the game, select 'Exit world'. You'll return to your homeworld again.

You're technically dead, so tu can do pretty much anything tu want. tu can't pause the game, o even peek into your Atlas though... tu can even step through other portals after the glitch is activated, tu can even go to other homeworlds. One little hit though, and you're dead. Oh, and swimming is a no-no. Cuz when tu jump into water, tu don't start swimming, you'll keep falling until tu reached the bottom of the lake. This can be fun at first, but after a few minutos of wandering around aimlessly, you'll get bored. What to do? Well, pause the game of course! Oh, wait tu can't... The only way to get out of there is turn off your game system. Seriously.

My advice: GO TO SEASHELL SHORE. I do it all the time. The fun thing is, tu already start the level in water, so tu don't automatically fall to the bottom. In this level, tu keep swimming. When tu start in Seashell Shore, swim over to that little shell castillo thingy at the other side of you. Avoid getting hit at all cost, tu don't want to get hit. tu will reach surface eventually. When tu reach surface... Well, go try it out once, I'll keep it as a surprise for you(trust me, you'll like it!). To end this glitch, step through a dark protal, o simply, let Spyro die.
