| |
| − | ** 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.
