Ok I play X5 a lot and I can beat the game flawlessly. But..
I have noticed something. I cant get the equip parts. At first I thought it was because I used the Black Zero cheat. But I tryed without the cheat and I still didnt get the parts. Whats going on here? As the title says, Glitch?

It is probably not a glitch. If you are playing the game on easy mode, you will not be able to equip parts. Plus, you need to wait until X and Zero are at a certain rank to equip more than one part. Plus, certain armor suits that X can wear can not use any parts.

First of all its not on easy mode. And second I know about that stuff. Its just not giving me the parts all together. I know what part you get depends on what upgrade you choose either life or energy. But it doesnt matter what I choose I still dont get Jack.

You are remembering that you have to wait one or two levels before it's ready, right? That makes a big difference.

No it's not i own the same game an i can get to the parts screen for your character I've even done it using Cheats for ultimate and Dark armors.

If you didn't already know. The boss must be at a certain level before you can even get a part. The boss has to be about level 8 (I think). You have to waste many hours till you can get it. With X, at nine hours it's time to get serious. With Zero, you could do it at ten hours.
