Cart internally has a 10k pullup resistor on /CS, and A11 of the rom chip is hard tied low via jumper (placed instead of a switch).
Curiously enough, it still has a pullup 4.7k resistor there, that now just connects +5 with gnd.

Also dumped an entire rom in case there is a different cart on the inaccessable upper part, yet unfortunately it turned out to be empty.
