| − | There seems little point in continuing the project here. A SVN project needs setting up.

| |
| − | |
| |
| − | I propose the following tasks to achieve the "OpenSource" goal.
| |
| − |
| |
| − | '''01)''' Do [[DS-Xtreme|Under The Hood]] research on the DS-X hardware for an insight into what the firmware may be. '''--DONE--'''
| |
| − | '''02)''' Acquire [[DSX_OSFP_FILES|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" updater application based on the knowledge gained.
| |
| − |
| |
| − | '''05)''' Disassemble the core8051 EZ-USB controller firmware.
| |
| − | '''06)''' Create a "OpenSource" firmware from the knowledge gained.
| |
| − |
| |
| − | '''07)''' Disassemble the configuration for the FPGA.
| |
| − | '''08)''' Create a "OpenSource" project from the knowledge gained..
| |
| − |
| |
| − | '''09)''' Disassemble the 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.
| |
| − |
| |
| − | This order was chosen because the firmware "'''[[:image:V112_update.bin| update.bin]]'''" is one large zipped?, binary file. So first we have to decompile the updater application to understand how it's zipped and what parts make up the USB, FPGA and NDS launcher....

| |
| − | At offset 0x000B79F4 in the [[:media:V112_UpdaterTool.rar| DSX updater application file]] you will find the URL that points to the DS-X server. This is where [[:media:V112_update.txt| update.txt]] can be loaded by the [http://wiki.gbatemp.net/wiki/images/c/cf/V112_UpdaterTool.rar updater application].
| |
| − |
| |
| − | In the file [[:media:V112_update.txt| update.txt]] there is a URL which tells the [[:media:V112_UpdaterTool.rar| DSX updater application file]] where it can load [[:media:V112_update.bin| updater.bin]] from.
| |
| − |
| |
| − | [http://shunyweb.info/forum/ Shuny] patched these URL's to point to another server where the older [[:media:V110_update.txt| update.txt]] and [[:media:V110_update.bin| update.bin]] could be found.
| |
| − |
| |
| − | Hats of to [http://shunyweb.info/forum/ Shuny] for a very clever and inventive piece of work.
