XOR Search with reverse HEX

[takumy]

I am searching a value R which is encrypted by XOR. 

Let the two XOR inputs be v1 and v2.

I found that R = hex(v1) XOR reverse-hex(v2).

In above example, 5F368E20h XOR 5F368EBEh = 9Eh = 158 (decimal, which is the value display in my game)

Is it possible to do the above XOR search? 

Thank you very much.

20 XOR BE = 9E. So if value less 255 you can search 9EX7 as Byte.

The contiguous bytes should be: 5F 36 8E 20 BE 8E 36 5F, why 9EX7 but not 9EX1?

On the other hand, how about the value greater than 255?

For example:

No. Continues bytes always reverse hex.

If value greater 255, then no luck for you. try search last part of number. 850 it is 352 hex, so search 52x7.
