An open-source port of Prince of Persia, based on the disassembly of the DOS version. - 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).
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.
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.
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.
I tried this some time ago. It's basically the same game, just with some QoL improvement like widescreen support, and also dynamic lighting which is cool.
I've been playing this on Vita and Switch for some while now. There's probably a port of this for anything, at this point. I think there even was a JS version that runs in web browser.
I sometimes watch ZX Spectrum playthroughs on YouTube. I know they're edited but seeing the games I played for hours being completed in twenty minutes blows my mind!
