To disassemble your firmware use IDA DISASSEMBLER PRO

How to integrate games and apps? I think this whole topic is all about that - no resolved yet.

is what the free version of IDA Pro Disassembler is valid for the RK2706 or is there another program?

flasher86, I have no time now:( University, mother, girlfriend, troubles with apartment's (maybe "habitation"? Don't know english well)... Will try next month, maybe. I'm very sad about:(

system information for my Archos 43 vision

manufacturer: ARCHOS
Product name:Archos43
Major version : ID 1.10
Hardware ID : 081101
Local memory:
Memory card:

use crack and get over those legal bullshit - regarding IDA Disassembler Pro. Legal ways are perhaps necessary for public projects, but if you want to do something in your home to your player, just do it. There is no better disassembler than IDA, it's author was genius!

Barracuda, I understand. I also have very limited time. Currently I am working on an assigned software development project, so I have to put maximum effort on it.

when I extracted the file Archos43.img. I got 4 folders: appdata, resource, system, system00, and 3 files: rk27boot.bin, rk28img.chk, version.bin.

Then with rk27uieditor2.exe I looked at my file bmp0.bin. And I saw that there were images of games, icons and SMS, NES, GB, which corresponds to 3 emulators.

my firmware is here: http://www.archos.com/support/downlo...0/Archos43.img

I would like to know how to disassemble for changing my firmware.

AleMaxx, my mp4 have a RK2706 chipset but not a rk26xx uses an 8051+dsp.

I see, Ive myself got a rk2706 player. This .img file you linked to in your post is a FAT image, if you mount it you should see something like this:

where "system/base.rkw" is the firmware. I've heard somewhere that this "new-style" firmware cannot be modded but I haven't tried this myself.
Also somebody mentioned to me that the free version of IDA doesn't contain ARM support (rk2706 main processor is an ARM, the DSP is a zsp500) but the demo version should work (Hex-Rays IDA Page : Interactive Disassembler download page). To load the base.rkw into ida, open the file, choose ARM as the processor type

and 0x5fffffd4" as the loading address.

then goto address 0x60000000 and hit "c". For further info you may read this: "http://alemaxx.al.funpic.de./rk27/rkwfwpatch.html

Good luck

I suggest processor type arm710 - because rk27 has arm7.
In my archive uploaded below is fully disassembled firmware from my player. Try it, if you want. But it is in Ida 4.9 format, I dislike Ida 5. And on Internet, you can easy find cracked Ida Pro 4.9 ~50 Mb.

Elfpack creator's released new version 3.0 - with support for dynamic libraries (as *.dll in Mustdie or *.so in *nix). Yet in alpha stage, but very interesting...
Time! Where are you?..:(
