Holy fuck, you guys (Gameshark Help)

[Ultimecia]

I never seem something like this, and I've been using gameshark since the times of the PS1. I stopped using gameshark when I discovered that I could download the codebreaker codes from the internet and upload them directly to the device, via flash drive. It's awesome.

But back to the gameshark, couldn't you try a code from a previous version of the device? Or maybe the codes are for example the version 1.0 of the game and you own the 1.1?
