Larger / New titles don't mount correctly when rebuilt

[LucaCorigliano]

I had this problem trying to rebuild DOOM while clearing the update partition. Some feedback is needed in order to pinpoint the problem

Can you provide more insight into how to clean the update partition and i will also run some tests.

I repacked LA Noire to test, and although it appears fine in xci explorer, it fails to LOad with "The game cart cannot be read"

Yep, what I tried so far:

• Cave Story (update directory empty except for a file) works without any problem
• DOOM (update directory empty except for a file) "The game cart cannot be read"

To whoever might want to collaborate:
This issue seems to be correlated to XCIHeader.CardSize which according to http://switchbrew.org/index.php?title=Gamecard_Format (look at Gamecard Header Valid Data End Address) is expressed in 0x200 (512) byte blocks.

What's weird is that in some larger games (DOOM, LANoire, Zelda) this field is extremely high:
0x29711809 * 0x200 (Zelda). If we follow this logic we got > 300GB of valid data, which of course is not right.

So what we are missing here is proper handling of that field. I think. I'll do some more experimentation as soon as I can, but help is always appreciated
