In order to boost the reverse engineering of code (especially the multiboot / wifi one), I decided to code a loader for the Interactive Disassembler (www.datarescue.com) to load NDS files.
It is based on DarkFader's great work on the NDS file format.
You can grab an early but working betaversion on www.backtrace.de/nds
cheers

This is great. Keep up the good work and keep us updated if you release any updated versions.

The loader has just been published on www.backtrace.de
www.backtrace.de now features a great paypal "donate" button *cough* ;-)
Have fun, I'm looking forward to some reverse engineering results :-)

update:
the previous links don't work anymore,
please use http://www.backtrace.de to get the loader and signature files.
have fun!

Are many people working on the Metroid executables? If so, would you be interested in comparing notes?

I don't think I'll be working on it :-)

zoo99: there is a freeware version of IDA 4.3
The loader comes with sourcecode.
mike: I wouldn't mind if you would post your findings here, dunno about
the legality tho.
#33487 - Vince - Tue Jan 04, 2005 11:15 am
Hi Bob,
AFAIK, the freeware version only supports x86 arches. I wanted to use IDA Pro to disassemble CIZ, the F2A Ultra firmware. Unfortunately, because of that limitation, I wasn't able to do so...

Oh, alright. Didn't know. Then there are only three more possibilities to
reverse engineer the code. I would choose between the two legal ones.
either buy IDA or get a different disassembler + DarkFader's ndstool.
If I were you, I would tend to buying IDA, it's worth the money!

great, feel free to do so.

Which version is recommended? I see a number of prices on the order form, but most of them look like upgrades. It appears that there are two main versions: Standard and Advanced.
Also, has anyone used the Linux console version in the latest version? I would like to know how well it works because Linux is my primary OS at home.

smileydude: depends on your available budget. if possible, i would buy
the standard version with a year of free updates (if it is still being offered).
the linux version is okay if you liked the old console interface of the windows and/or dos version. personally i got too much used to the GUI version.
so will you, after having tried it i guess. however, the latest beta version
I tested, ran fine under Wine ;-)
regards,
BJ ;-)

I believe standard is all you need, if your reverse engineering ARM code. If you need to reverse engineer MIPS code, then you need the advanced version.
#33558 - BobJones - Wed Jan 05, 2005 10:23 am
Yes, I've got the standard version and it has support for ARM processors.

So I decided to start looking at NDS roms. I used IDA for XBOX binaries (to disassemble to make trainers) and wanted to start poking around NDS roms.
With the XBOX there was a single flirt - so it was pretty straightforward - but I downloaded the NDS flirt and it has the following files:
libsnd.sig
libsndsp.sig
libsndsp_thumb.sig
libsnd_thumb.sig
ndsarm7.sig
ndsarm7_thumb.sig
ndsarm9.sig
ndsarm9_thumb.sig
So my question is what flirt file should I use on an NDS rom? I am new to NDS so I am not familar with the rom layout / structure other then that it is ARM. I believe 7 and 9 are GBA and NDS but not 100% certain nor do I know what the other flirt files are for. So if anyone can help and let me know which flirt file I should use on an NDS rom it would be appreciated.
For now I guess I will just try them all individually and see what results I get.
