This is probably a good time for me to lay out a piracy policy:
If the game does not have a legitimate English version and it's older than 5 years, direct piracy links are allowed.
If a game did have a legitimate English version but is on a system that is no longer supported, that specific version is ok to post. For example, Hakuoki on the 3DS is allowed because the eshop is closed, but Hakuoki on the Vita isn't because the Vita store is still running.
I personally think that piracy makes it more difficult for creators to be fairly paid, but also that it is necessary for game preservation under current copyright laws.
