Does anybody know of any todo-lists with protocols/file formats for bored reverse-engineers with too much free time? Ideally something a bit more accessible and in demand than old DOS business apps or the image format for some medical scanner (been there).
I know the first suggestion always is to 'scratch your own itch', but everything I use is either open source or at least open standards - so no itches. Over the years, I've cracked the encryption and analyzed the netcode of a handful of apps and games/MMOs, wrote viewers for their proprietary file formats, etc. and always greatly enjoyed doing that but that was usually just for me personally and I'd love to see someone actually benefit from this.
Maybe just some file converter for some proprietary Windows app or something.
