Erm. Slight problem. The resulting number appears to be 36 bits long according to the . Yet we only have 32 bit registers. However the first digit is always a 6 (first 4 bits are always 1110) so im guessing theres some extra stuff going on not included in that assembly code (unless i'm being stupid.) For now i'm just going to add 60129542144 (1110 with 32 0's after it) to it, which i'm hoping should work. however if you wouldn't mind investigating the bit which actually produces the URL to see if anything else is going on it might be useful.
