This developer appears to have accepted contributions from over 100 other people prior to having a change of heart about the GPL and ~~unilaterally~~ switching the project to a non-free license (CC Attribution-NonCommercial-NoDerivatives).

~~Somehow I doubt that all of the other contributors actually agreed to that license change 🤔~~

Bonus 🤡-points for making a bunch of unrelated changes to source code in the "Misc: Update copyright headers" commit.

edit: i stand corrected, thanks to @LiveLM@lemmy.zip i see the developer wrote:

I have the approval of prior contributors, and if I did somehow miss you, then please advise me so I can rewrite that code. I didn't spend several weekends rewriting various parts for no reason.

It's odd they didn't mention that in the commit where they changed the license.

🥂 to whoever carries on development of the last GPL version, and/or develops other free software emulators. and 🤌 to people continuing to contribute to this one after it became non-free.
