I clicked this link -> https://gbatemp.net/threads/release-dsp-firmware-dumper.402108/Q) I get "cannot initialize Sound module" error when using CIA/3DS version, how can i solve?
A) You need a DSP firmware (dspfirm.cdc) to use CHMM2 as CIA/3DS version. You can dump it using DSP Firmware Dumper, uncart, braindump or Decrypt9.
But I don#t really understand, what I have to do. As my registration-date suggests, I am quite new to this, so much stuff is still quite irritating to me.
