Executor is no emulator, and it does not seem that NuTek was/had one, too. It is just a (more or less) compatible clone of APIs. In principle as System 7 was one of System 6 - also not fully compatible.

Yes, that’s a similar effort …

And I disagree – it *can* be done: rewriting an OS from scratch, implementing a given set of APIs, and have some success. It’s been done several times e.g. with compatible UNIX implementations. One of it is close to total domination of the UNIX market, although it is not a certified UNIX and came laaaate to the UNIX market: Linux.

Or MagiC from Andreas Kromke et al.: a full replacement for Atari TOS (BIOS; XBIOS, GEMDOS, VDI, AES). It’s been quite popular on the Atari ST in Germany.
