Please read and understand http://chdk.wikia.com/wiki/Signature_finder before attempting to add signatures.

If the newer cameras are all fairly similar, it may make sense to add a new reference port.
Don't forget what the H stands for.

Oh, first I have to find and verify them :)
I'll probably just paste their code and let someone else do the signatures thing.

HarpoMa, that's what I am saying, your camera, and all the other cameras I've seen before didn't have trouble finding VERY standard functions, such as malloc, free, and i/o stuff.

Have you compare your malloc function to an older one?  I would be interested in seeing the difference.

Well, they don't look similar at all, although I didn't investigate much.

the malloc you found is certainly correct.  Very very different.  I've said it before I'll say it again.  Your camera is wow different.
