I'm putting the finishing touches on a project that has taken far longer than it should have, and just felt like showing off a little. This is a Cx4 dev board commissioned by byuu, and I finally got all of the hardware assembled and a ROM burned to it (I burned the ROM before mounting the chip to the board, I still have to work out the in-circuit programming). So technically it is currently nothing more than a MMX3 (USA) repro using RMX3 (Jap) donor, but it will (hopefully) be reprogrammable through the cart edge when I'm done for dev purposes. Sadly, there are no MMX2/3 hacks that actually run on hardware (SUPER bummed that the MMX3 Zero hack doesn't run on hardware...), but these adapters also work with GSU-2 boards, so the same mod could be done there for a Yoshi's Island hack, or Star Fox 2...
