Writing a Fuzzer for Nes Games
My project this weekend was a fuzzer for nes games based on seeded input from TAS movies
This was really interesting, and doubly impressive that this got built in a weekend!
“Overall this exceeded my expectations for this weekend. It demonstrated that, at a minimum the fuzzer can find glitches not in the original input, and can generate a new set of inputs that can be given to an external emulator to replicate the glitch!
As such the main challenge facing this fuzzer going forward are around optimizing mutation and selection to pick interesting runs.”Posted on 2021-11-23T21:04:28+0000
