Converting Nintendo DSi (Digital) (CDN) (Decrypted) to .nds file

[thanonyx thanonyx]

Does anyone know how to convert Nintendo DSi (Digital) (CDN) (Decrypted) files into .nds format?

You know, files like this. There are some DSi games I can only find in this format. I need to know how to turn them into .nds files so that they'll work on a DS emulator such as melonDS or DeSmuME. If anyone can help me that would be GREATLY appreciated.

A good amount can have just the 00000001 file renamed to NDS and there you go with twilightmenu or desmume.

Really, especially if it is decrypted like it says.Just take the 00000001 file rename it to your_own_game.nds and there you go.

I tried that, it didn't work. I use melonDS.

I also mispoke, though the difference should be nothing, people name DSI games with .dsi.

Do you have the system files required for DSi emulation?

EDIT:
I just tested on my own machine and standalone version of melonDS that indeed, both your dump and another type that usually has just the 00000000 or 00000001 file renamed to rom.dsi work if you set melon DS to (experimental) DSi mode, and have right dumps setup in it's settings (you need to point it to bios7i.bin, bios9i.bin, dsifirmware.bin and a nand.bin image)

I have all of that set up, it still won't work. I just get a blank white screen each and every time.

I had this behaviour myself in my testing when it was not setup right, for what it is worth. Also when melonDS is in DS mode instead of DSi.
I also tested on my functioning setup that it does not matter to melonDS if it is NDS or DSi file. Likely even 0000001 works.


I also found out there is likely some games that will just not work. One game would show a creating save screen and then white screen.

That's how I have everything set up. It still won't work.

I added that there may be games that do not work.
Which game you trying to run perchance?
