I made a tool that runs on SNES that lets you manage the data on a Turbo File Twin or Turbo File Adapter. You can view files, copy them to the cartridge, delete them, and view where and how they're stored in the Turbo File's memory. You can use it to copy Famicom Turbo File data to a Super Famicom drive, or back, and you can do backups of an entire Turbo File device and remove data left over from deleted files. The big feature I'd like to add in the future is a hex editor so you can modify and view files. Hopefully it's been fixed up enough at this point and all the major bugs are gone.
