Welcome to the Rockbox Technical Forums!
So you can actually make a functional MP3 player? How do you print the PCB's and write firmware for it?
I want to design a player that will do all the marvelous things RockBox is capable of. Themes, plugins, games, Video, Software codecs, you name it.
All of this is documented in the wiki. I recommend looking at the 68k targets first since they are most mature and have the most optimizations commited.
For the future I would recommend a dual-core CPU, because I've read that will be the fastest way to decode video and audio without an external chip. The problem is, nobody knows how to use both cores yet.

The problem with wikis (IMHO, and not just the RockBox wiki...) is that they're such a pain in the a$$ to navigate. You can only get to a page by searching for it. God only know how many "hidden" pages are on the average wiki, just because there are no external links...
For a music player, or even a full-fledged PDA, this is waaay overkill. I was thinking an ARM-9, prolly running at about 200MHz.

So I need a push in the right direction with regards to hardware. What kind of CPU does the community recommend? How much RAM? Hard-drive or Flash-based?
The problem with users is that they can't be bother to look for themselves. The iriver port is linked on the front page of Rockbox.com as well as the wiki. http://www.rockbox.org/twiki/bin/view/Main/IriverPort Next time look before asking.
FWIW the Ipod is a dual core ARM7 running at <=75MHz. If thats overkill, your ARM9 core would be roughly 3x more overkill Should make porting easier though. It'll be so many times faster then any other Rockbox target you won't really have to worry much about optimization.
It might speed up the port if you use parts already supported by other players:http://www.rockbox.org/tw.../bin/view/Main/DataSheets
IMO, dual-core is far from necessary and Rockbox doesn't even yet run on both cores of the portalplayer chips.
if I'm going to be deconding on the controller, rather than using a third-party chip
Saratoga, you sound like a jerk. Your elitist attitude does nothing. Why not help the guy? I think it is great that roach wants to make a player for Rockbox.This is my first post but a long time reader of this forum. I have a 2g Nano and patiently await a Rockbox version for it. But some people on this forum are quite snobish to say the least. This is not just my opinion either. Others Iv'e talked to have negative opinions about this forum too. Shame really, Rockbox is great and I appreciate the hard work that goes into making such a project. Some folks just need to chill a little...
