I was working on a Cx4 dev cart for byuu when I tore up a bunch of pads on the ROM footprint, and about halfway through the rework process, I just gave up. My OCD really didn't like the rework, even though I'm sure it would have worked fine. So I ordered a new Cx4 board for the dev cart, and decided to try something a little different with the chip from the rework board, and I built a breakout/dev board for it. Still waiting on headers, but this should be fun to play with. I'll probably hook it up to my Teeny++ so I can play around with it on my PC instead of having to do it through the SNES.
