DS-Xtreme OpenSource Firmware Project

DS-Xtreme OpenSource Firmware Project

The scope of this project is to open up the DS-Xtreme flash cartridge hardware/firmware for homebrewers to modify. I have asked the DSX for the information prior on embarking on this project. No information was forthcomming, "well actually the responce was Lameass from RABID1".

I propose the following tasks to achieve that goal.

01) Do Under The Hood research on the DS-X hardware for an insight into what the firmware may be. --DONE--
02) Acquire all the files that make up the firmware. --DONE--

03) Disassemble the PC application that updates the firmware. --IN PROGRESS--
04) Create a new, "OpenSource" firmware updater based on the knowledge gained.

05) Disassemble the firmware for the USB controller.
06) Create a new, "OpenSource" firmware from the knowledge gained.

07) Disassemble the firmware for the FPGA.
08) Create a new, "OpenSource" firmware from the knowledge gained..

09) Disassemble any native NDS application (the launcher)
10) Create a new, "OpenSource" launcher from the knowledge gained..

11) Using the knowledge gained make some schematics of the DS-X cartridge.

Work In Progress Log

5th January 2008:

Initial viewing of the PC Updater tool yields the following information.

1) The updater was coded with Borland Delphi development enviroment in C/C++.
2) The updater contains ZLIB compression librarys (probabily for the firmware).
3) The updater contains Altera Jam FPGA communication librarys (maybe for the JTAG connector on the circuit board).
4) The updater contains Mozilla/3.0 (compatible; Indy Library).
5) The Updater contains Cypress FPGA communication librarys.

On running the updater, it uses windows sockets api to download update.txt the update.bin from the DSX server. The mozilla api is probabily the wrapper to call the windows sockets api, to give platform independancy. Borland Delphi also has wrappers for the application windows. The applications resources can easily be pulled out with XN Resource editor. I've also noticed on some of the disassembly that the updater looks like it can take command line arguments?

ToDo:

I'm currently trying out a few disassemblers on the .exe to see which gives me the best results.
The hardware investigations need putting on the wiki on a seperate page.
The files need moving to a seperate wiki page.
