Hello, I am one of the developers from S1MP3.ORG
Welcome to our merry corner of the world!
I was wondering if it would be possible to extend the rockbox project to
these players.
I'm quite sure it can, given enough time and effort. But there are some
issues, and I'll address them further down.
Most of the players have an Actions ATJ2085 CPU chip
http://www.actions.com.cn/en/product.aspx?id=10 and can indeed play OGG
files (though their website doesn't say this)
I'd say that this CPU/microcontroller is the most limiting factor to get
Rockbox on these players: Rockbox is only built for and running on 32 bit cpu
cores, so this Z80 8/16? bit will require some work to get Rockbox for. We
once had it buildable for a 16bit CPU (calmrisc for one of the older Archos
gmini models), but that particular port was abandoned and most of the long/int
cleanups of those days are likely gone by now.
Is there even a gcc-fork or other free and good compiler for it?
Also, the limited amount of RAM might be a bit tricky to deal with.
Does it really play/decode the music with this CPU? Do you happen to know at
what speed it runs?
So, it will require a few dedicated and skilled hackers with this hardware to
make a Rockbox port reality.
These are just my opinions of course.
