Multi-Client Hack or Crackshiled?

Since i don't have much experience with VM software and im not sure if it would be feasible to run 8 VM's... Im looking for alternative solutions.

1st i found a hacked version of Vindictus.exe which allows multi-clienting, but it's from 2012 outdated, so could anyone make an updated version? or something similar?

2nd I herd of program/hack called Crackshield that stops hackshiled messages allowing you to multi-client, but i haven't managed to find any download links and im not even sure if it's up to date

Just wanna be able to run 8 clients on multiple user-accounts or one, doesn't mater.
