Homebrew Question about DSP1

[fenderjaguar]

I have modded various 3DS/2DS systems now, some of them for other people. When I modded someones 2DS, I remember being told by the guide to use DSP1, then delete the .cia.

I haven't used this with any of the other 3DS I've modded, including my own. Should I run this program? I don't really understand what it does, can someone help me? Do I need it, or is it optional? Is it just for using sound on the homebrew launcher or something?

With newer versions of Luma it's not necessary to dump the DSP anymore. It's used to have sound in homebrew applications.

3dsx homebrew never needed a dsp dump.
CIA homebrew still does, the newest luma does not change that.
There's a reason DSP1 is still in the Guide.

It dumps the dsp firmware to sd:/3ds/dspfirm.cdc so you can have sound in cia homebrews like freeshop (which is cia only btw).
It will self delete for convenience if you press B. Very easy and quick process.
You can find it in the FBI --> titleDB homebrew database so you don't even need to take out your sd card.

@zoogie, sorry for assuming, but what does this do then?

• Add DSP firmware signature patch by @MerryMage

That allows you to run a patched dsp firm I assume. That doesn't mean one isn't still required though.

You would need to ask @TuxSH what the patch's use case might be. I'm really not sure.

No it isn't. There's a 3dsx file available as well.

I wonder if it's possible to write a third-party DSP and this allows one to use it. This would mean that a legally distributable DSP firmware could be packaged with homebrew. I'm just speculating though.

That would be possible if someone takes the time to do it.

Anyone knows which HB apps need to use DSP firm? For example: freeshop , FBI? Or anyone has a list of them?
