Hi all. New to the forums and new to RockBox in general so, a few questions:

First off I have to say I love how RockBox supports so many audio formats. I mainly decided to install it on my iPod because of the freedom it offered: .nsf, .spc, and .sid formats are a very welcome addition to my iPod.
Now, my question is: Can I add more formats (yes, I want MORE)? Are there any codecs for sega genesis music, turbo grafx-16 music, gameboy, etc? .mod, .xm? Maybe an updated .sid codec?
If anyone knows of any programs/apps/codecs that allow playback of these types of audio please let me know!
Thanks in advance everyone,
Justin
