Changes

There are at least two hardware versions of the module, the original using a 1Mbit SPI flash ST M45PE10 [[Media:STM45PE10.pdf]] and a newer version which I had using a very tiny chip labeled "5A32" and I think "8936" but it might be "B936".  Note the circle in this image shows a 10k resistor from pin 5 WP to GND, which the ST M45PE10 datasheet indicates will write-protect the first 64K.  If you would like to disable this protection, remove the resistor and solder pin 5 to pin 6 VCC.

khmann had success backing up the 5A32 using the above pictured connection to a DS cartridge, removing the 5A32 and installing a ST M45PE20 2Mbit SPI flash salvaged from said NDS game with said data.  not sure what this "gets you" yet... but theorized that this change might have something to do with newer DSi units unable to use the CookingCoach dslink exploit
