Ps3 – the PS3 Jailbreak

Actually the only version being produced is the slim version ... you won't find a new -fat- version anymore... (unless someone sells them like diamonds). Anyways. The difference among the new models (slim ones) is based in their hard drive size. The actual versions are 120Gb and 250Gb ... but beware, this month Sony Japan will release new Slim versions in white color with higher high drives ... !!!

A lot of hardcore fighting gamers will tell you that you have to have a stick to be any good. You can ignore those people. As part of any company's standard testing routine, you must be able to do anything in the game using any of the supported input methods (controller, fight stick, fight pad, etc.). Not only that, but there are tournament players who win using pads. The trials are definitely possible.

What I would recommend if you're having trouble, is looking up a full trial run on youtube for your character. Sometimes just seeing how the combo is supposed to look is what you need to complete it. On top of that, a good way to master an extended combo is to break it into small parts (like single links or cancels) and then slowly put the pieces together.
