      A couple of days ago, i picked up this neat little player by Memorex. It looks alot like the attachment file. It is a 1gb player sporting a 1.5 inch diagonal screen. There is apparently a firmware called "deco"(although i can't find it). If any of you guys can find that firmware and dissect it then you might be able to find a way to make a port of rockbox. I was just wondering because i picked one up at a local goodwill for $15.00. However, I don't really know any technical specs. If any of you guys could even find this "deco" then that would be great. That way, more than one of us could work on the firmware.

markun:
The best way to find the technical specs is to open up your player and take some pictures of the chips so we can identify them.

Here's some more info about starting a port (and you don't need to be a programmer for the first parts)

Bagder:
The ATJ2135 is an SoC made by Actions Semiconductor and seems to be common in lots of Chinese "mp4 players". I've not found any data sheet for it.

Found some info about the ATJ2135 on this site: http://www.mcuol.com/News/185/14155.htm
