In my DS game, I have many different strange glitches. In my diamond game, I can catch as much arceus as I want in Spring Path and can catch all the regis. In my Platinum game, I can buy rare candies and master balls along with refighting trainers (except for gym leaders) as much as I can. Strangely enough, my Pokemon pearl game isn't glitched.
This was not hacked; I have no devices that can hack these games. This was how I bought it. I could go on several more pages about these hacks, but I want to get to my main question- what is this glitch? Do glitches just randomly appear in games?
Finally, I wonder if anyone has similar glitches. Please tell me, since I am dying to know. Thanks in advance.
