Are you sure? I examined the rules page closely and there's nothing to say you can't request hacked emus, loaders or whatnot. We've talked about Loaders before, and we came to the agreement that Loader links are prohibited since you can use Loaders to get unsupported games working. Hacked NRXs are a different matter, since in it's very core, NRX emulates all sets to begin with; the only reason why the latest EGCG hacks are available is because they fix innate emulation bugs that the original NRX had.
