Scratch

While this may not be strictly Scratch, I've noticed it happen in some Scratch programs as well.

In games such as Pokemon, sites keep finding bits of left-over data that was written onto the card, but never used (e.g. islands 8+9 in Pokemon FireRed, and a changing camera angle in Pokemon Platinum). Why, if space is such an important issue, do they copy all this 'dead' data onto every single card? I see this especially in the original Red, Blue, and Green versions, where there were two unused trainer classes, an unused type, and a battle with Professor Oak. Surely, in a time when computers had just gotten into mainstream consumer products, they could have made more use of the limited space? This, as I said before, also applies to Scratch programs, where we have a 10 MB limit.
