“Reverse engineered open source” isn’t a thing. You can decompile a program and look at the source code all you want, but that’s not the same as having the legal right to modify and redistribute it. Open Source specifically means the latter.
What you’ve linked to there is just some pirated proprietary-licensed source code that, frankly, I’m a little surprised Microsoft hasn’t taken down yet.
(Also, I don’t like the term “open source” for exactly the reason that it leads to this sort of confusion. According to both the OSI and FSF it means the same thing as “Free Software,” so folks should use the term Free Software instead since it emphasizes the four freedoms.)
If you want a pinball game that’s actually Free Software, check out Vector Pinball. I recommend installing it via F-Droid.
