So.... AO486 core... ScummVM(?) 0mhz collection... What happens now?

*MS-DOS 4.00 has been open sourced

ScummVM is its own separate emulator, so this isn’t relevant for that. MS-DOS 4.00 could certainly be used in the 0MHz collection for a good number of games, but I don’t think it’s necessarily going to run many games better than they already run using DOS 7.1 like most games in the 0Mhz pack already do. There could potentially be some games that are problematic with DOS 7.1 or 6.22 that run better with DOS 4.00, I suppose, but I’d be surprised if the number was very high.

Not much. Only some fringe legalities change but that isn't something most of this community sticks by anyway.

0mhz collection would probably be better off using FreeDOS than this newly open-sourced 4.00 if it really wanted to comply with Microsoft copyright.

Dave points out that this is not the popular MSDOS 4.01, but a 3.3 fork with multitasking support. --> https://youtu.be/BR6F0EdyulA?si=JdExVaQAFB0JYFol&t=251
