Hey guys. A buddy of mine has a Rockman X3 sample cart that needs dumping. Apparently it uses a CX4 chip, and this causes issues. If anyone has any knowledge that can help aid in dumping the cart (like what tools can be used) that would help. So far we know that the Super Wild Card X2 can dump this cart, but I have to doubt this is the only option. There HAVE to be more out there. If you have advice please let me know. If you have one of those for sale PM me as I'll put you in touch with my buddy that has the cart.
Maybe the http://www.retrode.org/ also work. Other way is to dump the eeproms with a reader. But than you need to know what you doing ^^. But i would prefer the SWC.
I suggested the Retrode but I have no idea if they can get ahold of one, let alone if it would support the chip. I dont recall but I'm going to say yes, and just hope I'm right.

Arduino-based SNES Cart Reader can dump CX4 carts. Details here: http://forum.arduino.cc/index.php?topic=158974.0 You'll need to use the "Enhanced" sketch.
