1. what version what..? A launcher works with any muonline version because its just run the main.exe with a simple process.start() call...
If you check the video you can see the launcher not english, but 2 min to edit the images and it will be english.
2. The post created 2 yrs ago, what you think how many hack was created under 2 years? A lot. This antihack system not good, use nsengine or liveguard or ugk antihack, the 99% of the free antihack are detected by antivirus because they are using old methods to detect cheats like how viruses working, and contain bad binaries.
So you can use MuEmu antihack what you can build from source and can make it work on your server (For free) or pay for liveguard / nsengine and use their system, both is great antihack system and block everything, not nearly everything, really everything.
