I'll extract the contents in a folder called romfs. With Command Prompt on the same folder, type up this command (Please make sure the romfs is named romfs.bin first!): Step 7: Copy the romfs.bin to the 3dstool folder. Then after generating it to a CIA, go to the decrypted folder. Copy the XORPADs and the ROM to the folder. Step 4: Launch the DS Profile Exploit (If you installed it), and I'll generate some XORPADS.

Drag the files for the SD Card's Launcher.dat, MSetForBoss.bat, ncchinfo.bin, and the slot0x25KeyX.bin (The slot0x25KeyX.bin will not be included in that folder) to the SD Card. Step 3: Rename the Launcher.dat to something else, like Launcher_GW.bat if there is one.

Drag the ROM to ctrKeyGen.py and I'll spit out an ncchinfo.bin. 2 ROM, 3DS to CIA tool, 3dstool, Reggie! Next (NSMB2 fork), and the slot0x25KeyX.bin. EXTRACTING THE GAME (HARD WAY, WITH OLD TOOLS)

Keep the 3ds_to_cia_2.07 window open until you inject the edited ROMFS back into the decrypted folder. Use this command to extract it:ģdstool -xvtf romfs romfs.bin -romfs-dir romfs Step 3: Go to the NSMB2 folder, the "decrypted" folder, and then copy the ROMFS to the 3dstool folder.
