Probably possible. :-)  You just need to know the physical addresses,
then read from the correct offset in /dev/mem, I would guess.

As for figuring out what the physical addresses are, you may need to
play with the console FORTH engine for a little while.  It probably
knows, though coaxing that information out of it would be nontrivial
and might be nontrivial even for someone familiar with FORTH.

Of course, if you're willing to open the case, you could just pull the
chip and plug it into something designed to dump ROMs.  This is a more
certain approach anyway - who knows but what they wired up the data
leads to the chip backwards for the sake of board layout or something,
thereby making the bits from the chip's point of view different from
the bits from the CPU's point of view....
