Hi,

In my opinion it is legal to disassemble a firmware for research practices, but not redistribute copy/pasted code from reverse engineering. Depending from where you live the situation may be different, hire a lawyer for more details ;)

I have a commented disassembly for ida pro of a m200 firmware, but atomicpunk's one may be more up to date :)

Hi All,

Just started gathering all the information from the forums into the wiki. If you have any files that require online storage please send me a PM as I am creating a share on MSN skydrive giving us about 5gb to play with. To be given access to add files please MSN or PM me a msn ID.

Any forwarded attatchments by e-mail will be put online when I have the chance. I want to create a one stop share for all resouces. Any feedback or suggestions would be appreciated.

sansadev@hotmail.com

Not setup a file structure yer but will do this as needs be.

https://cid-b1e4fc71fbc55227.skydrive.live.com/home.aspx This is an example of the share.

ATM there is full read rights for everyone and limited access to add/modify.

Hi again,

Well I'm not too sure about legality of publicly sharing disassembled code and such stuff so I think we should stay on the safe side and keep those for ourselves. But be sure I'd be happy to share our knowledge  with those interested in helping out. Simply contact me in private and we'll talk about this.

I didn't play long yesterday but I think I may have found something vaguely similar to a resemblance of an hold button handling stuff in the firmware ;) On the clip, I think it may look like something similar to pin 3 on port A ;) If that's the case, it would be nice because it would be very simple to read (activate the GPIO module, put the pin in the "input" direction and read it!)

I'll look more closely and try to find something similar in the e200 firmware so that Daniel could safely try it.

Llorean:
Yes, if you're disassembling the original firmware, it still falls under any restrictions it was distributed under which usually means nobody else can redistribute it.

saratoga:
You could probably distribute a diff against a dissassembly of the OF however.
