Yeah, the DIPs are pretty inconvenient. The two ways I can see to do
this from a hardware point of view:
1) add a boot ROM that is active after the Z80 leaves reset. The row
6 ROM has to be inactive or you get bus contention. Once the code
jumps from the boot ROM, the row 6 ROM has to cut in.
2) Put the menu system in the first page of the row 6 ROM. You lose
a game, but no new hardware is needed.
