Nintendo 3DS Factory Development Cartridge - FMCOM (V1 Type)

These are genuine Nintendo 3DS development cartridges originally used in Nintendo factory and testing environments.

This particular unit uses the CTRC-FMCOM-01 board and is 100% original with no repairs or refurbishment. These were most commonly used with the Gyroscope testing box. 

Included with this cartridge are two additional boards:

• TWLC-FMDUMMY-X2
• TWLC-FMDUMMY-X1

Specifications:

• NAND: Toshiba TC58NVG4S2ELA48 – 16Gbit (2GB)
• Controller: Megachips MA91707

Functionality Testing:

• NAND fully erased, programmed with a test ROM, and erased again
  

The cartridge has been left with a copy of retail Gyroscope software pre-installed to demonstrate functionality.

Version Info:
These are the V1 variant of 3DS development cartridges, very similar to the CTR FLASH CARD 16Gbit (E203344). This model does not include an SPI Save Chip. So games cannot be saved on these boards. 

This is a CARD1-type cartridge. (Note: Some titles require CARD2—those are also available separately.)

Compatibility:
These cartridges can be written using standard Nintendo dev kits such as the Partner-CTR or IS-CTR.
Additionally, I’ve developed a custom GodMode9 firmware, allowing you to write retail or debug .3DS images to this cartridge directly from a modified retail 3DS console.

These cartridges are ideal for development and programming use, as they are fully tested and do not contain any valuable or irreplaceable software—so there’s no risk of overwriting something important.

Condition:
Photos are a representation of the item’s condition—the exact cartridge you receive may differ slightly. As these are used items originally deployed in factory environments, they may show signs of use, including light scratches and occasionally small cracks. However, all cartridges are in very good physical condition, graded as B+.

3-Month Return-to-Base (RTB) Warranty Included.
