TIL there is an open source port of Prince of Persia

GitHub - NagyD/SDLPoP: An open-source port of Prince of Persia, based on the disassembly of the DOS version.

Based on disassembly of the PC DOS version, this port runs on PC, Mac and Linux and features many enhancements such as quick saving and the ability to mod the game including level design.
I remember this one. I don't know why they haven't been DMCA-ed yet because you can't make open-source programs based on the disassembly of proprietary projects (unless they have acquired the rights somehow which I doubt).
So it's not quite as clear cut as this. This is why even nintendo disassembly projects survive. There are allowances for this kind of thing.

You cannot change the license of a derivative work. That part is clear cut.
I cannot take a Harry Potter book, use Google Translate to translate it into another language, polish up the result by hand, and then claim it as my work at slap whatever license I like on it.
Is the original version even in print anymore? It’s really hard to believe that the “juice” of getting this taken down would be worth the squeeze.
It reminds of those stupid calculations that the music industry did back in the old days of Napster and other P2P sharing about how much money they lose.
When in actuality, I suspect that an actuary or accountant can estimate that this open sourcing of a 20+ year old game probably brings in new revenue in terms of consumers being interested in the franchise.
Once upon a time, you had to show an actual financial loss, to make a claim for damages. At least where I live (Denmark).
Maybe they've made copyright offense serious enough to not require that anymore. But without financial damages I would hope a copyright case would be frivolous. Apart from being a form of treason in the eyes of many lawmakers. Except when it's Trump, then it's just an honest mistake.
they should put it on a dmca proof place
