Thanks for all yr feedback, i gather you understood it well.
I know this sounds noobish of me but can some1 tell me how i can find an offset using a HEX editor?
Cause I kinda forgot how to search for them. BTW that will help write my next part of the tutorial.
16 MB - (offset backwards) 08
Example - 123456 = search for 56 34 12 08(no spaces)
32 MB - You should use 09 instead of 08, simple.
