I've finished writing a new sub-guide for BN6 hacking. I've been meaning to get it done because the information wasn't clear. The guide is about creating your own custom cutscenes. It shouldn't surprise you that it's all so fake. The result is believable because I've been using it in The New Crisis all this time and I still have people thinking it's a permanent game-hack.
You can see the guide in TREZ's Sub Guides section. You should be able to see it by simply registering.
See the guide!
