How do I use unsafe disk to crack Mech4 mecernaries?

[DoGGx23]

In the read me files it says use unsafe disk to remove cd protection then apply the crack. I downloaded Unsafedisk and when I open it up there are alot of folders.

Safedisc_v2_10_30
Safedisc_v2_05_30
Safedisc_v2_30_31

There's more but I do not want to list all of them. Which one do I use and how do I used this program?

you use the version of unsafedisc that the mech4 game has safedisc protection - but if mech4 is recent, there probably isnt a version for it.
