This program is a 1:1 Wii NAND Dumper based on YaWnD 0.3 with several improvements. All currently available Wii NAND Dumpers misunderstand the IOS_Read() returned error code -12 and cause dumped image file to be different from extracted image of external hardware programmer for de-soldered NAND chip.
After analyzing, the -12 code seems very likely to be ECC error but not simply to be bad block. And most pages with -12 return code might be unmanaged free block (ECC error due to erased but not programmed yet). Zeroing these pages is a bit dangerous. If it happens it's the very first time the ECC error occurred for a good page while dumping, zeros it might cause the dumped image useless.
Besides the -12 code, some people encounters -11 code and stop their dumping. The -11 code might be NAND read timeout and NAND status error. Stopping dumping is not a good idea but zeroing it would be safe. An extra Page Debug Dump is also provided for these -11 code for user to analyze it.
For whose NAND dump without -11 code, the RealWnD can help them make 100% 1:1 dump which is exact the same with hardware programmer dump.
Features
- Real 1:1 dump of NAND Flash by processing error code -11 and -12.
- Greatly reduce dump time by opening files once instead of appending repeatedly.
- Add log file for all error pages.
- Change to new style FAT management code for easily compiling.
- Add Debug Dump for -11 code or others for future analysis.
User guide
Most operations are the same as YaWnd. You can use button 1 to toggle SD and USB, button 2 to toggle +ECC and normal dump, and button A to start dump.
In addition, you can use button B to toggle on/off for Debug Dump. A log file WiiFlash.log will log all page error return code.
If DebugDump turs on, several image files WFD_<page#>_<error code>.img will be created for future analysis.
Controls
1 - Toggle SD and USB
2 - Toggle +ECC and normal dump
A - Start dump
B - Toggle on/off for Debug Dump
