Hmmmm, I guess because as Amiga Inc is still a company (well kinda, its just Bill McEwan and his grandma as far as im concerned
) which still has a commercial interest. And as they havent given permission (like Amstrad for example) its a big no no.
Whereas with the old games most of the software houses dont give a s**t because they cant make money out of them anymore - they only care if people try to sell them for $$$ instead of themselves. And most of em are sadly gone anyway.
I dont think the Amiga is the exception to the rule ya know. In most instances of old computer platforms theres always a different "status" in terms of level of dodgyness between the old commercial games and the OS needed to run them.
