Okay...well....looking at this Zelda 1 cart, I am going to make the board a 512K cart. I see that there is space for a 32-Pin EPROM. Is that for 256K EPROMS? If so, does the wiring change since it is using a 128K 28 pin MROM at the moment?
Should I use the 256K pinout on the board with the 32-pin extension and wire up char line 16 up to the extra address pin to get a 512K ROM/cart?
And if I do, to get Char 16 high/low, what register do I write to in what CHR-ROM modes (Since it uses CHR-RAM it doesn't matter).....
I am kind of confused how this will work....I know it will but it seems like it shouldn't some how. It's magical.
