Since the code is constantly changing, I didn't upload a compiled binary to itch.io. You need a working C++ compiler to use the tool anyway, so I thought it made more sense to let the users compile the tool. You can find build instructions on sb2cpp's GitHub page.
I made this tool solely because it seemed like a fun project to work on. Small Basic is a very simple language mainly made as a way to get children interested in programming, so this tool doesn't really solve any real world problem. Furthermore, although I have never used Visual Basic myself, I assume Small Basic is nowhere near as powerful or complex as Visual Basic. However, Visual Basic does seem to be supported by Mono, a widely used cross platform implementation of the .NET framework. You should check it out if you want to port your Visual Basic games to other platforms.
