.mod file format ?
dma:
Great to have a SID emulation codec!
The emulation isn't the most faithful, but it isn't bad either. :)
I can now browse HVSC in my H120 to discover new gems, yeah! :)
Could the "durations" file of HVSC be implemented in the codec btw?

I have created a working codec using DUMB that plays .mod, .xm, .it & .s3m, BUT (and its a big but) only for the simulator. DUMB uses some floating point functions (floor, pow, log, exp) in order to play these formats. The modified rockbox version had these functions #define'd to something else which breaks playback. As I believe we don't have the floating point functions available for the host devices (ie ipod, iriver, etc) as there is no FPU, I don't think we can use DUMB in its current form.

About half a year ago, I created a plugin (not a codec) which includes realtime playback with sound in simulator, plus a disk-writer (since it's not running at 100% speed and also because play_pcm() in CVS was broken for plugins at the time) for the target device (h340). The disk-writer on the iriver produced a bit-perfect raw pcm file compared to the same code running on the simulator.
I solved the floating point issues by porting the necessary maths routines from FreeBSD's math library as well. Unfortunately I kind of lost interest, but I posted what I got to the tracker at http://www.rockbox.org/tracker/task/2793 .

Cool. I'll have a look at what you have done. It doesn't sound promising about the memory allocation / free thing though.
I also have another library I want to try out, which is xmp.
Starius:
If you guys ever do get amiga mod (.mod, .it, .s3m, .xm, etc) supported in RockBox, I'd consider buying a ipod just to use it.
I see this thread hasn't been updated in awhile, any progress here?
