SAMP-VS (Version Switcher) is a simple application which allows you to switch between 0.3.7 and 0.3DL.
Normally, you would have to load the version of SAMP you want to play, and then change the directory in the settings menu to the folder which contains that version.
SAMP-VS does this for you, by setting the directory for 0.3.7 and 0.3DL. After that, you can simply click the button to launch either version and the work is done for you.

This application was made because I don't trust 3rd party software, and wanted to be sure I could have a simple, working application without running the risk of viruses or malware.

I'm now sharing this with the world.
