I've been working on a file manager and backup tool for Turbo File Twin and Turbo File Adapter, using the same visual style as my previous WildStorage tool for DS. Includes a library for making it friendly to work with Turbo File in SNES homebrew games.
I need to finish adding the file operations (copy, move, delete; skipping hex edit for now) and test it thoroughly (the TFII filesystem code is untested and almost certainly needs work) and then I think it'll be a good basic version of the tool.
