The Turbo File devices from ASCII Corporation are external storage devices for saved game data on various Nintendo consoles. They have been sold only in Japan, and are mainly supported by ASCII's own games. The first one was designed primarily to allow players transfer data between the Wizardry games released on the Famicom (and later Game Boy and Super Famicom).
Turbofile is for the Famicom, and was released in 1986. It contains 8 kilobytes of battery-backed SRAM. It connects to the Famicom's 15-pin controller expansion port.
It is supported by:
The Turbo File II was designed for the Famicom. Same as Turbo File, but contains 32 Kbytes battery-backed SRAM, divided into 4 slots of 8 Kbytes, the slots are selectable via a 4-position switch.
Turbo File Adapter is for the Super Famicom, and was released around 1992. It allows to connect a Turbo File or Turbo File II to Super Famicom consoles. Aside from the pin-conversion (15pin Famicom to 7pin Super Famicom controller port), the device contains some electronics to add a SNES-controller ID code, and a more complicated transmission protocol for entering the data transfer mode.
It is supported by:
Turbo File Twin is for the Super Famicom, and was released around 1995. It contains 160 kilobytes of battery-backed SRAM.[1] 4×8 kilobytes are used in the four TFII-modes (emulating a Turbo File II with Turbo File Adapter), and the remaining 128 kilobytes are used for a new SNES-specific "STF" mode. The STF mode is supported by:
Turbo File GB is for the Game Boy. It connects via the link cable port. Data is stored on memory cards that connect to the device.
