The Nintendo DS Cart Whitelist is a system title (HNHA / 0003000f484e4841) on DSi and 3DS TWL_MODE that contains a list of whitelisted DS carts. Other carts can be loaded if they have a valid RSA signature, which is how newer DS games load on DSi systems.
Format
Newer versions of the file contain 3 sections: NDHT, NDHX, and NDHI. Older versions only contain NDHT.
Header
The header is 136 bytes.
| Start | Length | Description |
|---|---|---|
| 0x00 | 4 | Section type (NDHT, NDHX, NDHI) |
| 0x04 | 0x80 | RSA signature of the entire section below this point. |
| 0x84 | 4 | Number of entries |
NDHT entry
NDHT entries correspond to titles and are 48 bytes. The NDHT section is always first.
| Start | Length | Description |
|---|---|---|
