Wolvin's Simple SourceSDK UI & Workshop Uploader Tool (Old Version)
This is my very old program that helps manage & aimed to your Source SDK mapping purpose. This require Visual Basic 6 RunTime (Redist. Included).
Please note that use at your own risk. This program is no longer updated/maintained. Usage for Legacy Source SDK purpose only! (tho, I'm still using it for Garry's Mod mapping anyway)
