This is a tool for converting 3DS ROMs to a CIA format, designed to be user-friendly and does not uses Python or .NET Framework or any other programs and scripts.

With version 4.0 it is able to patch minimum required kernel version (FW Spoof) and RegionFree, which requires *.exefs_norm.xorpad's. FW Spoof function checks FW version game requires to run and only applied if original value exceeds entered (2D02:FW8.0-8.1, 2E02:FW9.0-9.2, 3002:FW9.3, 3102:FW9.5, 3202:FW9.6-9.8).

With version 5.0 of the program XORpads are no longer required if proper boot9.bin file detected in the same folder.

User guide

To use, you will need to obtain boot9.bin file from your 3DS (require B9S hack installed on your 3DS to generate the file).

Just hold Start+Select+X on boot and it will be saved to the /boot9strap/ folder on your SD card. Alternatively you can use GodMode9.

Put your boot9.bin file in the same folder as the .exe, then press Convert 3DS ROM to CIA button.

Select folder with *.3ds files and wait for program to finish.

Note: Program scans every subfolder, please avoid folder with too many subfolders. Also Download Play is supported.
