The 7800 OS turns off the extra internal RAM when switching into 2600
mode, since the address space for normal 2600 games partly overlaps
with the extra RAM. If you had a game with a proper encryption key
that would have all address lines connected to the cart and that in
it's first instructions turns on the TIA but doesn't turn off the
extra RAM, you could write 2600 games that use the RAM. But if you
are going to crate a game that works only on the 7800 console and
that has access to the MARIA, why would you want to limit yourself
to 2600 mode graphics?

Would it then be possible to write a game that flips back and forth between 7800 and 2600 mode, maintaining state?
