I was a huge Amiga fan for many years, and well past its best-by date. I’d love to at least play with AmigaOS 4 to see what it’s like, but wish it ran on hardware you can find at Central Computers (or on, say, an ARM Mac).
I find it really hard to support these companies who are keeping these repositories of historical importance under lock and key.
... while bickering about who owns AmigaOS[0].
Evidently there is some commercial value, they're making enough money off sales of the 30+ year old software they didn't even create to waste it all suing each other all the time
If you pick up Amiga-Forever from Cloanto, it is repackaged with a new UI, official ROMS (Cloanto owns the Trademark), and a bunch of pre-configured machines.
Amiga OS 3.X and 4.X are different beasts, and both continue to get updates.
You also, need to buy (legit) roms from amigaforever, and a copy of Amigaos4. Cost <$100 CAD.
[] You need to run Amigaforever on windows at least once to generate the Cyberstorm PPC ROM for AmigaOS4, but it may work on FS-UAE on macos/linux afterwards.
Icaros can run native (booting directly into it), virtualised, or hosted on Linux (or Windows, but I think that is less than optimal still)
