I'm also interested in this, got an xbox on it's way to me. Lots of options and there all similar prices?
Also is the TX J-R Programmer V2 the one to get?
X360ace v3. Cheap £6 and does exactly what is needed. Glitches your Xbox 360! You can play with the timing files for best results too. Reflashing the chip is easy
Well,already got the Coolrunner,but thanks to your guys input if its a faulty board or has long boot times i'll return the Coolrunner and get the X360 Ace.
