Another trick is:
1. Start Spyro 3
2. Wait until you see the logo "Insomniac"
3. When this logo starts to move, pop the lid of the playstation, wait 5 sec then close. The game will now play

This trick works for other games such as Coolboarders 2001
Find out where the antimod logo pops up then do this trick about 3-5 sec before it.
