None of this makes any sense.
Emulators and bios are 2 different things. Emulators are legal when the dev creates all of the code himself without any insider technical specs and information of the hardware being emulated. Bios is the basic core "operating system" of the emulator, it is software and is copyright protected.
Nope.
Some cores do have bios built in, the dev of the emulator took extra time and effort to create their own bios from scratch which is legal and is different from downloading a dumped bios.
Just because you think it should be free and just because some rom site had them for download does not make it legal.
This is correct except that Flycast is not a core of Redream, they are 2 completely different projects. Dolphin and PPSSPP devs created their own bios.
Nope.
No, this is also illegal and we will not jeopardize Jasons business by doing so.
Firmware and bios are essentially the same thing, proprietary software written by the hardware manufacturer and is subject to copyright laws.
This is just so much nope and wrong. Basically what you are saying is "nuh-huh, it's legal cause I think and say it is so what you ares aying is wrong"
A quick Google search will show you that bios is illegal just like a rom or any other copyright protected software unless a company has legally released it to the public.
