Is it possible to get a patch for this, I have decrypted the rom with both ndstool and encryptds advance and I get a different CRC, so can you release a patch or perhaps say what method of decryption to be used.

same here, origininal proper is encrypted, the secure area, ndstool & soldisnake's tool don't get the published crc32, sha1, mds5

Both tools are wrongly zeroing some bytes when decrypting. I guess that the tools think that they shouldn't be there, but they have to in a proper "NDSi Enhanced" cart dump (tools were designed to follow original NDS cart specs).

Just do the following:

1. Decrypt as usual.
2. Open decrypted dump in hex editor. Go to offset 0x4000.
3. From that point, copy a block of 2048 bytes (=800 if your hex editor displays block byte size in hex)
4. Open the encrypted (Legacy) dump in hex editor. Go to offset 0x4000.
5. From that point, select a block of 2048 bytes and paste.
6. Save the edited Legacy dump, which is now in decrypted format.

I understand whats happening, but I haven't been able to decrypt it to get the crc on DoM. Should I use a certain program? Are there settings I'm missing?

I can decrypt it but not get the HEX bit. Pity the fixed version has not been posted to Usenet or the likes. :)

@rimsky82: Use eNDryptS_Advanced_v1.2_NDS-iND (unzip to a folder, copy .nds file there, run .exe and follow menu)

@Geddy: get a hex-editor. http://mh-nexus.de/en/hxd/ is free, fast, lightweight, clean and feature-rich enough. Quick hex-tutorial:

- Open decrypted .nds: CTRL+O and browse.
- Select block: CTRL+E and type 4000 ("start offset"), 800 ("length" radio button). Be sure "hex" radio button is selected.
- Copy: CTRL+C
- Open encrypted .nds. Select block like above. Paste (CTRL+V). Save .nds.

Many thanks for your help. I have managed it now. :D

hello has all I would like to know on which Rom (crc) is necessary it applied the method

my rom decrypted crc : 602c82
kazumi213 @ 2009-11-19 00:21:39

The whole process is to be applied to the recent release by Legacy (CRC-32: 0C02D4EB).

hello cool Thanks kazumi213
