Okay, I'm going to try my best to explain to you how the save file works. I will break down each section and show the difference between what the game reads and how you think the game should read it. The whole save file is what the game is expecting to read. If you open a save file in messaging environment, you will see how the game reads the file...

What is the groups of a base affix? It tells the game to use this stat with this range. Let's say I want 2000000 damage on a sword, so I change the first base affix to 2000000. Let's see what happens... Let's change that to hex 00030D40 Spoiler 01 0A 08 08 01 10 D4 80 F4 C0 07 20 00 28 A0 04 30 00 38 00 42 B9 01 08 A3 F0 BD F1 04 12 07 08 04 15 63 C5 40 0A 1D 00 03 0D 40 1D 72 8E 1D 21 1D 72 8E 1D 21 1D 72 8E 1D 21 1D 72 8E 1D 21 1D DA CC 07 63 1D 72 8E 1D 21 30 0D 38 00 40 9E B5 BC C8 01 0A The item didn't load in look at that. I want 2000000 damage, so how do I get it? Well the fact of the matter is that you cannot change the affix to just anything you want that the game cannot read.. It is expecting a number that is predefined in the affix table.. Now, I still want 20000000 damage! How do I get it? You can't without rolling the seed field and change that random number after adding the highest affixes in the affix table... How do I roll the seed? Well you pick a random number between 0 to 4294967294.. Changing the seed will change the stat. How do i make it exceed the what a single stat can do? double up the stat. I want 127 stats that are all different? After the patch 2.0.5, 6 stats on the item is all you get.
Thank you. There is a whole lot more, but without explaining bit for bit, byte for byte it's enough to see why it is what it is...
this is absolutely veeery well written and uber interesting!! thanks mate i really enjoyed reading it. as you stated, i'm aware there s a ton more to it, but it's an outstanding explanation nonetheless. cheers man
