Changing system requirements and Virtual machine notice

Recently, I checked to see if Solar 2D was able to be run on Windows Vista. I found that not only was it able to run on the OS, but it was also able to be ran though Virtual Box through 3D acceleration and 128 MB of VRAM

I have tried to get it to work on Windows XP virtual machine, but I could not get OpenGL 2.1 to work on there, but I couldn't get OpenGL 2.1 to work. All it did was show the game window with a black screen and a debug console, though it's likely a problem with VirtualBox and not XP not being able to run it at all.

Edit: Forgot to mention this but Visual C++ Redistributable for Visual Studio 2015 also needs to be installed. I had no issues doing that on XP.

Hi. It works on XP and Vista but those are not officially supported platforms.
I don't want to commit to support 23 yr old OS
