When you said 'game', I thought you meant that you had actually made a game, not just a hack. My guess would be that the reason your hack hasn't been approved is because the ROM hacking maintainer quit a couple of months ago. You'd probably have more luck submitting your hack to a site that people actually visit.
Yes, they should just pluck one off of one of the maintainer trees that grow in the maintainer forest, because it's extremely easy to find someone who's competent, capable and willing to put in hour upon hour of voluntary work to maintain a site that nobody gives a shit about. If people want ROM hacks, they should go to an actively maintained ROM hacking repository, not an emulation site that rarely put any effort into its ROM hacking section to begin with, even when it wasn't more than a decade past its prime.
