Could someone please explain the damn codes for me? It says at the title screen ... does that mean where it says "press start" or when you have the screen with the "player options, level select" options?
I also can't seem to get any of the codes to work. Does anyone have ANY working codes??? Please email me with your help! Thanks

The only code that works is the Gyu one listed on the cheats section for this game.

AMEN! That is the only code that actually does anyone any good. None of the real cheat codes work.I was really getting excited for an infinite air and health cheat. I could use those for some of the levels.But nooooo! Noooo! Forbid that! Codes for ecco have been posted as recently as one to two years ago. But they have not been verified to work! What on earth? Do people really like screwing with others? I've posted help on other game site forums to the pros to see if they really do work or its just me because I'm making it harder than it reallt is, but I don't think I am because they need to be more literate and detailed with the freakin codes!

Yeah there's a lot of bogus Ecco the Dolphin codes out there. I'm surprised out of all the garbage no new codes were found. Could really use an invincibility code.
