Correction: Thanks Tchoin, but I strongly suggest Old Engineer (who sadly doesn't post nearly enough these days) & Pikkon and many others way ahead of me in terms of Xbox material On the arcade front, the users with the most technical knowledge are Jamtex, Serantes and Retro. Playstation 2 tends to be Port187, Unclejun (one of the most helpful users here) and a whole host of others who contributed to the Tool discussions a couple of years ago. I've moved away from development material, but always willing to chip in if I remember something someone else detailed or can remember some of it myself, but I am a jack of all trades and master of none! The above guys really should be your first port of call (if they are willing to assist). I still come back here as I still think it's one of the best sites around and I love to see other people's collections / discussions on dev stuff. A fascinating subject imho. One thing I do suggest however is that new users (or old) NOT ask me for SDKs or illegal software (it's been happening a lot recently). :thumbsup:
