for the game vexx.i cant find what button to push to find where you input the cheats

As far as I know, there's no cheat screen for this game. If you've found one, tell me how to get there and I'll help you navigate it.

You must beat the game once to unlock cheat screen.

I've heard this rumoured several times, but no one's ever described it in sufficient detail to convince me there is such a thing.

There's plenty of instances in the older threads on this forum of people desperately in search of such a thing but being unable to find it or unlock it no matter what they do.

I think it's a myth - unless you can definitely describe where it appears, what's 'beating the game' exactly means that will unlock it, what cheats are provided in the cheat menu, etc.
