Description
I have been using Claude for the past couple of days this week to document and modify the TR2 game file format for an obscure Japanese-exclusive Wii game called And-Kensaku, or 安藤ケンサク. And-Kensaku is a game related to Googling. There are a few game modes, but the most famous one asks you a question and gives you two answer options, and you win if you choose the most popular Google search. I have been able to do the following: 1. disable signature checks on the files, and 2. allow edits to the Phrases.tr2 file, making it possible to modify the content of the aforementioned game mode. I wanted to go on this little adventure because reverse-engineering file formats is an extremely difficult (at least for me) and time-consuming task, and I wondered how well Claude would do at it. Right now, not everything about this game is documented, but I would like to fully document it and maybe release an English patch.

Could you build this?
Partial While LLMs can help write unpacker scripts, reverse-engineering proprietary binary game archive formats typically requires specialized binary disassembly and hex inspection. The author even noted using Claude to assist, but discovering the underlying format specs requires hands-on reverse-engineering.
What it would actually take: A developer needs tools like Ghidra/IDA Pro to disassemble Wii PowerPC binaries and Dolphin emulator memory dumps to identify how the TR2 file format is structured. Once the header offsets, compression (e.g., Yaz0/LZ77), and byte-alignment schemes are mapped, custom unpacker/repacker scripts are written in Python or Rust. The hard part is the initial reverse engineering of proprietary byte layouts and decompression routines.
