Rockbox Ports are now being developed for various digital audio players!
SHA1 is 160 bit.
if you read mcuelenaere's post above, he's already tried several 160bit hashes and found them NOT to match
I've tried SHA-1, TIGER and RIPEMD160. You could try others yourself if you want to, but I'm having the feeling here that not very much people are comprehending what I'm saying.
We understand you fine - remember that we have reverse engineered a few other players before this... But I figure there are more than one way to run these hash algorithms on the data (like order of data, range of data, with or without padding etc) so I don't see how any random test-shots can exclude any particular algorithm until more details are discovered.
By the way, if no one else figures out a way to get code running on the ZVM, I was going to suggest that someone get a broken player, desolder the flash ROM and then dump it with an EEPROM programmer. The chip is TSOP with just an 8 bit bus, so it wouldn't be that hard to do. Hypothetically, would you be willing to do this, or else mail the EEPROM chip to someone with the equipment?

I will mail the flash ROM to you.jwh

Is it best just to keep trying codes and seeing if the match up? To me, that sounds like a lot of guessing.
So what does the coincidence mentioned suggest? I do not really get it. Sorry.
