This is a simple program for extracting/injecting SecureInfo_A (4.x only). It simplify the process without having to about cutting/XORing whole FAT16 partition every time (it only requires the untouched encrypted NAND.BIN along with corresponding nand.fat16.xorpad).

SecureInfo used for system region changing (JP/US/EU etc). Basically, you install few system CIA files for your target region (3DNUS/UpdateCDN), extract and inject new SecureInfo_A to emuNAND from target region donor, write emuNAND back and Format System Memory in System Settings.

User guide

First downgrade to 4.x FW and prepare 4.x emuNAND with DevMenu/BigBlueMenu.

Then download and install following system CIAs using 3DNUS for desired region.

Now extract your emuNAND from SD card, inject into emuNAND target region SecureInfo_A from donor system, insert emuNAND back to SD.

Load emuNAND and perform Format System Memory/本体の初期化 in System Settings.
