Hi Brian
We ran out of Microsoft wireless controller matrix2 circuit boards. We're going to be switching over to a Ragnarok modchip that works with CG2 circuit boards, but it's going to take a couple of weeks. I got the new modchip prototype in today but I need to work on modifying the software to work on the CG2.
We can probably round up another matrix2 modchip if you really want it, are you sure your circuit board is a matrix2 circuit board and not a cg2 circuit board?
