Same thing for an 8k rom with two 4k games? I'm considering
double-ended carts more for the novelty value than a serious attempt at a
multicart - if all youw ant is multiple games, then you may as well go
with a 128 or 256-game dipswitched multicart. I was just wondering how
feasible it'd be to make a "deluxe" version of Oystron or something, with
maybe a beta version or Mondo Pong on the other end. If that costs less
than $2-$3 more than a standard 4k cart, it might be worth doing.. if the
difference is gonna be much more than $4, it wouldn't be practical.

This looked pretty difficult to me... no?

Ooh, I see possibilities here if you or someone else gets a bankswitching
design working well and cheaply. Imagine putting an 8k version of Oystron
in a 16k ROM, and using the other two 4k slots for hidden games - if
joystick button 0 is held down on powerup, it switches to a bank with a 4k
beta version of Oystron.. if button 1 is held down, it switches to a bank
with Mondo Pong.
