Ok I have updated the script but the only problem now is the compression algorithm because lzo1x doesn't work.
The following is the link to the script, feel free to test it:

Seems found algo, but one problem - 1 call is virtualized

Edited: See below

[aluigi]

It seems a standard algorithm to which have been applied some XORs.
There is xor 0xd7, then there is an interesting xor [ebx] 0x14 and so on.
Anyway it doesn't seem lzo1x.
