This started when I saw the warning that GetVersionExW was deprecated, then looked it up and found StackOverflow answers saying that you should basically detect the feature directly instead of checking the version, which makes sense to me. Then I found that I could probably detect color support by using GetConsoleMode and GetStdHandle. But then I asked myself what the point was unless you could get color output directly in the terminal, which it seems like you really can't if your app is a GUI app. (I have no idea why Windows makes this pointless distinction between console and GUI apps...) I tested Command Prompt, PowerShell, Windows Terminal (which is just PowerShell again), and even Git Bash (MINGW64), but none of them will ever give the console output of a GUI app such as VVVVVV. The closest I got is that Git Bash doesn't seem to detach the process, but it will simply produce no output. At this point I feel like it's not worth it keeping this code around if it didn't even work in the first place, so I'm removing it. People can always enable color by using the -forcecolor command-line argument anyway.
