Actually, I just finished the 3dn file, and was just about to upload it! I don't believe any of the sprites are different, they just add in some new sprites. (Such as the map, save slots, things like that) It doesn't change any of the standalone sprites, so the 3dn file will thankfully be backwards compatible, and will run with or without Plus installed. Also, I needed to ask, am I allowed to include the Metroid Plus files in a zipped folder with the 3dn file? Or should people just find and download it if they want it themselves? (The creator of the mod snarfblam says 'feel free to steal or sell my work' but I would still credit him, of course!)

Hmm... I may need to just have someone else do the video, if they were so inclined, I can't figure out how to even record and set it up correctly in the first place.... So for now, I will just show off screenshots in the repository. If someone makes a video though, I will make sure to credit them! But for now, I should probably just stick with writing. x3
