Alright, so this is awesome!! I purchased these two controller adapters in hopes of getting to play GameCube games with my original Xbox controller. Well I received them a couple days ago and I'm here to report that it WORKED!! Currently I'm using Devolution r197. Recently, I've considered upgrading to r200 because I was interested in using something other than the GameCube controller. I have a Wii Classic Pro controller, and a PS3 controller, but I didn't see the point of upgrading to r200, then having to re-verify all my games, just so that I could use controllers that I didn't want to use. So instead, I stayed with r197 and started looking at GameCube controller adapters. I found a bunch that were PS2 to GameCube, but I didn't want to use the PS2 controller. Yes, it's triggers are analog, but the travel distance of the DualShock 2's L2 and R2 triggers are in no way comparable to the GameCube's triggers. Then.. I found another adapter that went Xbox to PS2. My hopes were that I'd be able to daisy-chain these two adapters together so that I'd have one combo adapter that went Xbox --> PS2 --> GameCube. And as I mentioned earlier, it WORKED! The two adapters I used were the "XP Joy Box" (Xbox to PS2), and the "GameCube Joy Box" (PS2 to GC). I feel that the button mapping across all the adapters, is perfect. As long as the Analog switch is turned on, on the Xbox to PS2 adapter, everything will work perfectly. I tried it out with Super Mario Sunshine and it felt great. The analog triggers acted exactly the way they were supposed to. Since these adapters were daisy-chained, I was expecting for there to be some lag, but I was pleasantly surprised when I didn't notice any at all. Not only did I not notice any lag, but the analog sticks on the Xbox felt more responsive then the GameCube ones. I'd describe it as "Fast" or "Twitchy". Which can be good or bad depending on who you are. You may have noticed, on the button mapping chart, that the X and B buttons are switched. The buttons are mapped according to the location of each button on the controller, and not the button name. The GameCube's "B" button corresponds with the location of the Xbox's "X" button. So it all feels completely natural. So far I'm completely happy with this setup. And I'm more than excited to get to experience awesome GameCube titles on a controller that I actually enjoy. Hope this helps those that are looking for another alternative to the GameCube controller.
