Can't be that complicated. The parts in your picture only have room for 10 bits of state (two in the 74'74, eight in the 74'273).

PAL16L8 doesn't have any latches, apparently.

"Tetris 2" in multicarts is usually Tengen Tetяis with the title screen stripped out so that it fits in NROM. (It appears the multicart makers never found LJ65, unfortunately.) Contra is a 128K UNROM.

In theory, it wouldn't take that much state to select among these games: 6 bits for a 16K bank number, 1 for selecting H or V mirroring, and 2 for selecting 16K NROM, 32K NROM, or 128K UNROM. (At least that's the approach 100-in-1 Contra Function 16 uses.) To fake state on a latchless PAL, can't you just designate an output that loops around to an input? In any case, most of the bits could go straight to the ROM through a '161 or '377.

One day, it will be MINE!

Right, but you can make some inside since it has feedback inputs.

Why did they use a separate EPROM for menu?
While they made a lot of NROMs to run with CHR-RAM
