Think, there are alphabetical dragons for spyro 1, alphabetical orbs for spyro 2, but nothing for spyro 3, so I sugest alphabetical eggs, it could be either the names of the eggs themselves or the names of the missions they're attached to, all levels cheat would obviously be allowed

The all levels cheat doesn't do anything until you've beaten the game which requires a lot of eggs being acquired not in alphabetical order first.

cant you overwrite a save?
