it's hacking current PC based games for commercial gain basically..
I've even seen a number of sites refuse to cover it because they keep teasing latest games to get more people to donate for private builds..
so it would probably be best to not cover it
it's one of the darker sides of emulation, which seems to be making a full force comeback lately.
I guess without MAME to show people how things should be done in a fair way without trying to profit from it, it was inevitable (I say without MAME because MAME doesn't really handle newer platforms, and this approach would be unsuitable anyway)
the world could do with less of this bullshit.
