'[PIC]: Interfacing MMC card written by FlashPath a'

Hi there.. Im a college student in Canada in the Electronics
Technologist program .. myself and 2 partners are building our
graduation project.. (a control panel that allows programmed or manual
fire of pyrotechnics)and to allow the end user (our sponsor..) to
program a Cue file on his PC we're implementing an MMC interface ..

Problem is i can find little info on the data structure of how the
Flashpath stores data to the MMC card..

Using an PIC16F877 and plan on talking to the card via SPI .. does
anyone have any tips or locations where I could find some info on this?

The only Flashpath manufacturer to reply to me said "I doubt the data
would be changed from its format on the computer" .. which doesnt say
much :)

Thanks in advance for any assistance..

You might run a search on google for some mp3 MMC projects...   I just did a
quicky and got this project using an atmel controller:
instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2000/peterdan/
final.htm

I'm sure there are others.  Any particular reason for the MMC instead of
something like a compact flash? <--lots of examples of those available...
