CHR banking

Where do the 512-byte banks get the extra bits to specify a full address in CHR? They need an extra bit from somewhere (maybe they're fixed at fixed at 0 or 1 or A9 ?) —Lidnariq (talk) 15:06, 14 October 2015 (MDT)

The 512-byte banks would be limited to the first 128 KB. The mapper is really intended to be used with a 32 KB or 128 KB SRAM for CHR, and 128 KB is already a crazy amount of CHR RAM so I think this limit is okay. --NovaSquirrel (talk) 16:31, 14 October 2015 (MDT)
