That’s because these consoles and source code are not always compatible. To make them it would cost them time, money and the compromise to maintain them.
I would rather these companies to be forced to open source their older hardware and source code, so the community could do something with them and not have all the hardware laid to waste. Or at least support the development of emulators
Yes exactly. These companies hold rights for far too long in the hopes they can “milk that cow” at any chance they have. The products of these (and many others) companies are electronic waste for many after a while and so normal copyright laws shouldn’t hold for them, it’s just too wasteful.
