Restunts
From Stunts Wiki
Restunts is the name given to a project originally started in the community with the purpose of disassembling Stunts and then translating it to C and thus obtain a source code we can handle and modify. This was desired because attempts to get to the original source code failed and it appears to not exist anymore. Nowadays, the term sometimes extends to other related efforts, which include modification and recompilation of the assembly source code as well as recreation of parts of the code.
