| + | == 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. |
