I agree, there a lot of c64 and Amiga games still copyrighted including all of the 'Ultimate Play the Game' owned by Raven and Hewson's entire back catalog.. not to mention System3 and Team17.
iUridium for example was a crap conversation, retro games only work on retro hardware with a joystick..
They will make some cash and those Android owners whom don't own an Amiga may buy them.. but that's about it.
