The problem with a few of those formats is that you do have to emulate
certain portions
of a console's chipset in order to play back files. With the limited
power of some of the
Rockbox targets available, this will prove very difficult, if not impossible.

For example, PSF files (PlayStation Sound Format) are PlayStation
executables, which means
that you have to essentially emulate the R3000 MIPS CPU the PS1 uses.
Info source is here:

Most of our targets may not be able to handle PSF formats in realtime
as a result.

However, Rockbox already does support the following chiptune and game
music formats, and some
of them will already cover a few consoles for you:

* ADX (used by many Dreamcast, PS2, GameCube, and Xbox games, as well
as a few Saturn games)
* SID (Commodore 64)
* NSF/NSFe (NES)
* SPC (Super NES)
* MOD, S3M, XM, IT (via MikMod plugin)
* SAP (Atari POKEY files)

And I'm sure it's been mentioned already, but there are a few patches
in the tracker that will add the following
chiptune formats:

* HES (TurboGrafx-16)
* GBS (Game Boy/Game Boy Color)
* SC68 (Atari ST(?))
* VGM (various consoles)
