Formally SAMP-VS. 3MP-VS adds support for UGMP, and possibly VCMP in the near future.

This update allows you to set a directory for GTA Underground, to quickly and easily load the Underground Multiplayer launcher, and join your favourite server!

Easily and quickly load whichever version of SAMP/UGMP you like and get into gaming without the hassle of manually changing directories!

Update (17 Jan): UGMP was failing to connect to a server. The tool now loads UGMP with elevated privileges which seems to have fixed the problem.

Update (22 Jan): Added the ability to disable buttons of the versions you don't use, and updated the name and the icon to the new name.
