no, you need to run this exe from your command line, if you're not fimiliar with this, you can create a bat file in a folder with both files (decompress.exe and msg_kernel.dat), create a text file like this:
decompress.exe msg_kernel.dat msg_kernelNEW.dat
and save it as mario.bat, then run it.
After this you will need to launch au3 scripts, but you will have to PM for details, as I can't post files here.
