help unlocking mogul spc/msl code

[isosdcftp]

I've figured the parameters out, it uses a 8 character string(ESN Maybe?) to calculate the code. However since I don't know what the code is used for, I dont know if it gives the correct one.
I've attached the tool I created.

These are the two Structures given as parameters:
.

struct Par1{
char * str1; // Always point to '1234'
char * str2; // 8 char string used as input
};
struct Par2{
	char * outstr; //out, Initialize to 0, Dont forget to free after calling GetSPC
	BYTE OutSize; //out, initialize to 0
	BYTE Unk; //Unkown, initialize to 0
};
