What's a trainer and what is it for?

It's like a built in gameshark code, inf health inf ammo, etc.

Normally found in shops, people sometimes wear them for the name i.e. Adidas, Nike but they are normally worn for sports!:D you've gotta laugh!:D

Be carefull what size you order!......

A trainer patch give you option of selecting certain cheats to help you through the game, in my opinion they are all a waste of time a spoil the game! (but thats me...)

i disagree, trainers are quite helpful. for example you may have a boss you cant beat or a level you cant pass, so you might turn on a cheat or two. but if you use it throughout the whole game then you are spoiling it.
