A question to people doing these nice conversions: why don't you guys contact the rights holders to ask for the right to make an official conversion? Many of them would be fine with it. Eric Chahi and Jordan Mechner have proven to be very tolerant and would probably agree to it, moreover, equivalent versions on GOG (
https://www.gog.com) are sometimes available from even very big houses such as EA, Befhesda and the likes at quite a low price fully compatible with the costs of media.
I doubt they would bother to sue after a refusal anyway so that wouldn't change a thing at worse and at best the Amiga would finally have an official version. Could even be available on GOG (via a UAE wrapper a la DosBox) so that could bring you a bit of pocket change and bring some people back to the Amiga.
It can only bring good things for the coder who would do it and the community so why not?
I mean your versions are nice but official acknowledgment would be a real improvement and motivation both for coders and users and would serve as well to advertise the Amiga on official game press sites (cf Putty Squad).
Are any of you guys planning to do it?
