I uploaded my BadType challenge from last weekend's Dragon CTF Teaser on GitHub. It's a medium-difficulty RE task for Windows x64 (worth 400 pts), solved by 9⃣ teams during the competition.

How do you decompile the font? I tried ttx but hit Had to write small & dirty disassembler myself :(

Wow impressive, that's a valid way too. ttx used out-of-the-box throws these exceptions, but you can nop out the invocation of the op_ functions, or the "raise" inside of them, and it should decompile fine then. That's what did while testing the task.
