Banking CHRRAM

If, for some reason, you were to remove the 8KiB CHR RAM IC on the Sunsoft-3R PCB and replace it specifically with a 62256 (the largest compatible 28-pin RAM), the functionality of that PCB would then become:

 $8000-FFFF:  [.PPP .C.C]
    P = PRG Reg  (16k @ $8000)
    C = 8KiB CHR RAM bank

No-one has ever done this.—Lidnariq (talk) 12:12, 12 May 2013 (MDT)

Are you capable of running a test ROM for bankable CHR RAM? It could be used as part of the test suite for this mapper's NES 2.0 representation. --Tepples (talk) 15:24, 12 May 2013 (MDT)
