This looks awesome. If people are interested in this and haven't checked it out yet, http://microcorruption.com is still running: 19 levels of security challenges on an emulated MSP430 board.
To the people who are wondering if they'll be able to finish the CTF, here are my two cents: go ahead and try for a few hours. I'm sure you won't regret it. I haven't done assembly since the beginning of 2012, and I was able to do a couple of levels in less than an hour, and before I started I new absolutely nothing about MSP430 assembly. The tutorial/manual are so good that I believe even someone who doesn't know assembly at all might be able to finish at least some levels.
