Must be different RIVA version.
Reason why NOD missions doesn't load is that scenario files from NOD's GENERAL.MIX aren't loaded. You can extract those with XCC Mixer and m2 will load. Probably something with paths.

It would be great for fans to have a fully working game, and I've heard a lot of things about the NOD missions and the story line, so I think many will be interested in those. I downloaded XCC Mixer but it said I need the C&C CD. I only have the ZIP files from the abandoneware sites online, and I dont have a clue about editing games, I just play them. :) The FMVs you sent in that first update were for both scenarios, and so those cant be viewed. Is is possible please to update the main game archive file to include the missing NOD files? I'm sure all of this stuff is copyright free by now.
With Riva, I got the latest one from Animet. The screen being double in size is almost like it is meant to be in interlace? Or like it is showing a PAL screen on an NTSC setup. Heroes of Might and Magic 2 plays fine with all cut scenes so not sure what to suggest there.
Just tried the latest EXE you sent, but now everything is messed up. The FMVs play in a small window over the top of the main screen, I'd guess maybe Riva was meant to be set to full screen instead of windowed mode?
I couldn't load in any missions as the game just quit with an error/software failure. #80000026
