PSN emulation thought.

How do you know that? (Just an innocent question, I never researched about this).

You can think of xlink kie or similar application which relay on system link. Though I do not have rigid knowledge on this matter. In case of system linked multiplayer games, two or multiple ps3(or xbox360 or pc) can play games together. Why does this happen? Surely xlink-kie guys do not reverse every psn/xbl stuff and make their own online sprx,eboots,xbe,xex etc with which ps3 interacts. They are merely a medium to connect consoles. Sort of: role of tracker in bittorrent system. Now this type of online interaction should be easy to emulate, as it is generic. I referred to this point.

uplay type DRM system can also be reversed. But it should involve specific games, it is not generic. "Code for prince of persia" NOT EQUAL TO "code for assassin's creed". However, not everybody loves every ps3 games. Curious people can give it a hand for their preferred game. Lets say people A, B and C reversed prince of persia and D,E reversed assassin's creed. It is not hypothetical, people have done it earlier. We can refer "ubisoft server emulator". Just the bad point is, you gotta hunt for specific games.

I guess the hardest type to beat is: A game heavily tied to online. Even physics interaction, particle system, shaders etc.

Now about ban wave. I have been with ps3 scene quite a lot of time. I witnessed the epic failure, ecdsa, collapse of chain of trust, lv keys leaking. Anyway, I think they detect some kind of ID, folks refer as "console ID". In xbox, there are processes(think of trusted male-ware from manufacture) to detect the firmware version. But in case of ps3, I don't surely know if there is any background process. But there is some way to know ps3's firmware version, the games/video/audios you are playing, virtually everything. Now you can really manage all of them upto "cell boot ring". As of I know, this has not been compromised yet. And somehow I think it will not be compromised either(sixth sense stuff ). So it is very highly probable that you will be banned if caught using cfw or emulator.
