i need a UPX unpacker/decompiler to unpack MLE ( moon light engine) and make it's GUI undetected (for maplestory)

if you can give me one or say me how can i edit the size of it and others that will be great

i want a program like ResHacker but its doesnt unpacks it...

(if you will say its not legal or other shit then give me a working UCE lol)

Go to the 'Reversing' subforum. I'm sure there a tutorial somewhere that shows you how to acomplish your task.

Doesn't UPX packer also unpacks?

UPX is not an executable protector, just a packer, the packer itself provides unpacking functions:
http://upx.sourceforge.net/

If, however, it is modified to not be recognized by the UPX executable, unpacking it is easy as hell.

Open in OllyDbg,
Search for command POPAD, there should be one with a jmp directly after. Breakpoint the JMP.
Run till breakpoint, step once, dump at that address, rebuild imports.
