How does the DS cart handle ROM loading? NeoSD needs the sets to be converted into *.neo files, but I know nothing about how this works on DS' cartridge. I'm guessing it's plain, unpacked files in the folders named like the *.zip files for corresponding games? At least that's how his other multis work, and it's probably how this one works as well, but it would be nice for someone to confirm. I'd peek into the Neo "roll-up pack" they've posted, but I'd need an archive.org account, and I can't be bothered.
Also, I know there are very few freely released
homebrew productions on the Neo, especially MVS / AES, but I wonder if these work at all. A good thing to try would be the
240p Test Suite. It works on the NeoSD.
