These hacks aren't yours, you shouldn't submit other's people's work here without the author's permission, and considering these are a bunch of Japanese hacks created since 2008, I highly doubt you have the author's consent.
If somehow, the author of these hacks, gave you permission to upload them, contact me with a proof (like a screenshot of the author stating you may upload them here) and we'll give those hacks a normal moderation process.
I honestly hope he did get permission, and hope that all (example maybe the Kaizo edition) can be accepted. We don't have a lot of Japanese hacks here, and it'd be a shame if these were lost (if they are of any worth, of course).
Yes, but the thing is most Japanese hackers are very reclusive and don't want their stuff to be distributed outside of their community, some Japanese sites even have English text written in big red letters saying "Do not redistribute". This, and the uploaded not being Japanese, makes me think it's really unlikely he got permission from the creator. I could be wrong though, but as I said, that's really unlikely.
It'd be nice to have more hacks and all, but we must respect the creator's wishes.
