Nintendo M82 BIOS?

[Troglodyte]

Hello,
Since I don't really have the money for a Nintendo M82 and the unit is so rare, I was wondering if anyone here knew if someone has dumped a Nintendo M82 BIOS ROM and put it up on the internet for download?

It would be cool to try to create my own custom M82, or maybe hack the power pak to display the M82's boot screen and play the accompanying music.

Short of this, I suppose if the music is available, that a recreation ROM could be created somehow.

UPDATE: I found it. For anyone else that wants to know, just try searching for the following:

M82 Game Selectable Working Product Display

Hopefully I can now find a ROM image of the Nintendo M8 Display Unit.
I liked the music that came with this unit's boot screen better than that
of the M82, but the M8 Display Unit seems even more rare.
