Hardware Revisions

DSi

    • board C/TWL-CPU-01 (Original rev, all pictures below)
    • CPU: TWL. The latest date code picture I could find online was "0836 1m" as shown below, however other pictures with CPU covered show the NAND codes as late as 916, so...
    • Suspect this is the only board where WiFi chip is available in Hybrid games like CookingCoach
    • Wireless card DWM-W015


DSi RevA

    • board C/TWL-CPU-10 (Newer model, can someone provide a date or serial # range?)
    • CPU: TWL A. Mine is "0940 2m". My US Serial # is ~ TW71848???[5]. If yours is earlier, please update this.
