I'm happy the many ZSNES-dependent translations got to be hosted here a little while longer until someone else years later stumbled on them and fixed them, rather than being immediately removed in the name of emulation accuracy. I could still use them with those deprecated emulators that way as opposed to playing them in Japanese.
Retroactive enforcement of this "rule" ... opens a big can of worms. Might as well go and delete Super Boss Gaiden because it turned out to be too buggy for real Snes CD hardware.
But this is 2017. People don't like that options they don't like to exist, and can't just go their way and ignore it. The option has to be removed. In this case, it's about emulator accuracy. Apple delisting tons of games incompatible with their iOS #255 is suddenly okay, we can purge it off the database and just expect long retired developers to come back and fix this stuff to keep with the new developments.
There's already non-compliant reports and negative reviews for quite a few hacks here just over the ROM information including the ROM name and set and CRC, but not the SHA-256 hash, and that makes scraping this website's database harder for them. I mean if you're willing to try and have a hack taken down because of that detail, you don't care about it in the first place.
