So, the games don't start. Radiant Historia says that it's an encrypted rom and avalon code just show me the screen of translation credits, seems to work, and then it shows me the same screen over and over.

It tells you what you can do with encrypted ROMs when you get one. Those are your options.. we don't want to chance including the data needed to decrypt ROMs in case it's regarded as copyrighted by Nintendo.

For the other one, you can try checking "ignore gamecard limit" in the options (or whatever it's called). Some patches make the game larger than the header says it should be which messes up the gamecard size protection, which some games rely on as an anti-piracy measure.

The problem is that Radiant Historia rom is not encrypted, I also decrypted it, but it continues to say that.
With the avalon code rom, I tried to ignore gamecard limit but it didn't work D:

encrypted does not mean zipped.it means its encrypted like it needs nds bios encrypted.

I can't understand why the stock rom doesn't show me any error but the pached rom does. Maybe it's the patch dunno.

It's because whatever you used to patch the ROM is encrypting the secure region. A real DS will only play ROMs that have been encrypted like this.

If it still says it's encrypted then you didn't really decrypt it.
