Also, I don't know what kind of adapter you want to buy but those I have require a wired xbox controller anyway to work.
Aaaand, I don't know what kind of controller you are using now, but if it is a third party controller, there is a high chance that it won't work with the adapter because those are mostly only made for the original sony controllers.
I heard some say there is a slight delay at specific products. Not many adapters around (only xbox360 to ps3 for some reason). But I'll keep searchin' for a good one. Oh and besides, I have a great pal that has an xbox360 controller. He would lend it to me. So if I'm able to find a good adapter, I'll get it; if none are around, I'll just pick the controller instead. Thanks for responses
Maybe I'm clumsy, but I used two different adapters back the time were I played on XBL and I never noticed any kind of delay. That's just what I can say from my experience.
Banned? Why would you deny a player to use the tool he needs to put his best skill into practice? Is it because one is afraid that players get advantage out of turbo modes or similar, which are often implemented in such adapters? These rarely work, and they won't in DOA.
