why do all ISO's have to be 1.35GB?

    why is this so? i nkow that i have wipped garbage bytes from numerous GC backups and they run faster so why is it 1.35GB? Full size ISO's(1.35GB) tend to load slower on my GC and i get DRE's with em but when i wipe'em they run just like an original! I dont get why this is so cause people say that full ISO's are better than wiped, but for me its not true.

    TELL ME WHY!

    For some games, it's a matter of encryption, where it uses absolute byte values and you need the image to be the full, original size. For others, it's because a lot of chips won't even boot the disc if it's stripped, so it needs to be the EXACT size of the original, which is the full capacity of mini-DVDs.

    It pushes the data to the outer ring of the disc making it read better and makes it where you won't get DRE(Disc Read Error).When you strip the image it is closer to the inner ring of the disc,and most likely not always you will get DRE.I'm not 100 percent certain that wiping a GC image is actually wiping garbage data also.

    i have a Xeno GC chip and wiped games tend to run better than full size ones.
    wouldn't the data closest to the inside rim be better? it is the first burned and will have less errors? i feel that data on the outer rim of the disc isn't as good since it is written last.

    Due to planar density, the data on the outter edge of the disc is read/loaded faster than what's on the inner edge. And the overall disc quality depends entirely on the production method and dyes used in the pressing of the disc itself. In a normal, fairly high quality disc, the quality over the entire written surface is the same. It's only when you have low quality discs that there are issues, in which case the problems could be at any point of the disc at all. Again, due to planar density(which just means that on a disc spinning at a fixed rate, the sectors closest to the outer edge pass by the laser faster than the sectors closest to the inner edge, when being read), it could just seem like the quality degrades as you move to the edge of the disc, because there's more data in less planar space.
