That's correct, except that you have to use the Supercharger RAM write mechanism, not a straight STA $F000, because the read/write address line is not at the cart port. Someone else can better fill you in on the details if you need. >I don't think you can address all 6K at once linearly because the 2600 >prevents that.

I think so too, though I'm not the SC expert around here. - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
