What are the capabilities of a gameshark?

[White & Nerdy]

(Also, I have another question here: https://www.gtplanet.net/forum/showthread.php?t=130711)

Could a gameshark be used to reverse engine wear, make used-only cars available new, or undo the dreaded oil mod? This ties in with my other request, allowing me to use cars exactly as the AI races them. Also, no GT4 guide yet contains detailed stats on the AI cars.

What about increasing the length of the sim mode races? More laps = more fun!

Changing the regulations of the Supercar Festival to allow concept cars so you can use the Nardo and Cien like the cheating AI?

All those and possibly more are relevant to my interests. Please help!

Yet again, I can only partially answer this. The gamshark can allow you to get all the used cars with no miles. It doesnt allow you to get the nardo or the cien in the super car festival but it can decrease the AI intelligence or increase your acceleration by up to 16x. here is a link to a full list of gameshark capabilities for gt4.

Also, Cheating like this is usually frowned upon. I have this knowldge merely because I use two seperate saves One for testing tunings and the other for actual racing play. I suggest the same for any one who like to tune cars and also race them. Also, running two saves allows you to buy cars from yourself so you know what you are getting and you get it cheaper.
