struct MSG1 MSG1Block[X]
X being in increments of 0-20.

This one is for Hjukebox2.jrs, which is a block in nk.bin ; )
--- Quote ---trying the template you suggest gives me a syntax error on line 30...
[29] for (sz =sizeof(s)-1,up=0;upstrng[up] = s[sz];
[30] }
[31] return strng;

Normally, this one should work; which version of 010 Editor are you using? Maybe try a fresh start and restart the app or so : )
--- Quote ---It is possible that not all of the NULL block is the checksum. I've seen in the past that buffers are included at the start or finish to fill out the checksum making the original unknown. If I can get access to the information you do, I'll try other checksums.

Could be, I don't have a lot experience with hacking DAP's. But this way looks very believable to me, the structure looks perfect and so; but I could be wrong : )
--- Quote ---Would collecting all the different checksums from various people not help to narrow down the possible algorithm?
--- End quote ---
I don't know if that could help, but maybe it can. Do you mean collecting all the checksums from the different versions of the firmware?
But I think hacking the firmware update program is going to be more productive ; )
TheBlackCat:
I was wondering, is the MTP requirement built into the hardware or can it be changed if the firmware is replaced?

It is pure software; if the Rockbox USB stack is going to get into SVN & the ZVM target will get ported I don't think MTP will get supported anymore :)
LambdaCalculus:
I was curious about something. If the MTP stack is in software on the ZVM, would this also apply to other Creative NOMAD/ZEN players? I have been trying to gather up info on the Dell Digital Jukebox to help start a port (the thread's at http://forums.rockbox.org/index.php?topic=11368.0).
At the risk of going a bit off topic to the ZVM, would any research done on this platform apply to nearly any NOMAD/ZEN platform? The Dell DJ is OEM'ed from Creative, uses MTP to transfer media, and is TMS320-based. So can this info be spread across the entire line?

I don't think hardware MTP devices exist. Its just a protocol run on top of USB, theres no sense in making one.
