itch.io

More info: I tried the following:

1. Re-downloaded the community file as Mega Man 2 community.3dn
2. Copied and pasted the rom as Mega Man 2 community.nes
3. Loaded that rom. The community file loads fine.
4. When I load my original work, it is rejected and the game appears to be default, as I described earlier.
5. Then, when I load the same community file again, it too fails and the game reverts to default!
