I'm with EliteRacer. Sure hybriding is easier with a sharkport, that's why I do it that way. I have hybrided some nice cars with my Codebreaker as well, and it's not all that hard once U get used to it. I know several people as well that can't use a sharkport (no PC, just Web TV), which is the main reason the codes were hacked in the first place. The fact of the matter is, they are both different tools, and though hybriding is easier with a sharkport, how do U use it to put on a no tire wear or lap modifier code, or get infinite health in some other game? Best case scenario is to have both tools, but I've always felt if U can't afford both get the GS2.
BTW, most people have little or no trouble with their GS2s, and certainly the problems some of U have had has led to your frustration with it.
