Virus has generously released a tool he developed to decode and encode Panasonic DVD player firmware. This unique tool has opened for the first time the possibility to modify and enhance Panasonic DVD player firmware.
It also offers the options to auto create a header, auto update the checksum and more. The software is able to recognise so called multi-update firmware files. These files contains multiple updates for different versions.

To be able to modify the encoded firmware, it needs to be dissembled. Virus suggested the following tools to do this:
Get IDA Pro Advanced (version 4.7 - 4.9) and use MN103 chip dissembler module for IDA Pro Advanced (available at Hitmen).
Click here to view a tutorial using this method by Virus.
Download the MN103 chip dissembler here (made by smo.free60 from xboxhacker.net).
Modify the main.lua file and use loading address is 0x40000000. More instructions follow.

Very use full is the DVD-S49 service manual with all printboard diagrams and the complete service code section (features many more codes than the ones found in the service manual). At the Panasonic Microcomputer technical support website you can download the MN103 processor instruction set and it's architecture.
And last, but most important the is hacking section at the forums. In here you can discuss, post new info and ask questions about all your firmware modding experiments.
If you have successfully modded the firmware, than please submit it to the site so it can be made available for everyone. You can upload your firmware modification trough the forums or email it to panasonic@dcevolution.net. Firmware modders can also acquire there own page with webspace if they want to release the firmware by them self. If you want to apply, than also mail me.
What kind of firmware you may release, I want to prevent it got shattered over the internet without knowing what version/improvements it has. If you release the firmware trough your own site, than please let me know with an email or a post at the forums.
