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. > But... > > Molding new cases is, I think, a little beyond the scope of this project. > Unless someone here knows something I don't, it's gonna cost BOOKOO BUCKS Okay, okay, okay...

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. -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html Don't post pirate BINs to Stellalist.
