Anyone know how to convert those DSiWare .cia files to regular decrypted .nds?

I'm not interested in playing on a real console, instead, I want to test the games on No$gba, but it only loads .nds files. So far I've been unable to find a tutorial to convert from .cia to .nds.

I downloaded a tool called dsi_srl_extract, but it didn't do anything, or maybe I don't know how it works.

Can anyone provide a step by step guide as to how to do it?

But you asked in that thread too.

So what? He's asking a legitimate question.

Yes I asked there too, but since it's the opposite of what that thread is about, I decided to make a new thread about it and possibly help other people looking for the same information.

And in case you are following me around, I also posted the same question over at 3dsiso. See? I saved you the trip ;)

No, the thread is about converting .bin/.nds to .cia (the opposite of what I'm asking).

i think i saw it before but i cannot find it now.
to convert the decryptred dsiware to cia, we use makerom, and the -srl command?
how do we do it exactly?
just -srl, the input file and the output file name?

Why not just download the nds game from the multiple sites that are hosting it?

Here's what you're searching for. And I already said, that should be in the guides subsection :).

From looking at these cia's, it's just a matter of chopping off the first 0x3900 to get back to the original srl. Hex editor level work.

Wait does converting them to .nds mean we can play DSiWare on a DSi console?
If you inject them into DSiWare games or convert them into CIA's, they would work on a 3DS. I'm not sure about playing them on a DSi though, but I don't think that there is a way.

Ah ok, thanks. I thought maybe there was a way to convert them to be a DS ROM file or something.
