MMC3 clone, model 9112

                  .--\/--.             
   (r) CHR A10 <- |01  40| -- VCC
   (f) PPU A12 -> |02  39| -> CHR A16 (r)
   (f) PPU A11 -> |03  38| -> CHR A11 (r)
   (f) PPU A10 -> |04  37| -> PRG RAM /WE (w) ?
   (r) CHR A13 <- |05  36| -> PRG RAM +CE (w) ?
   (r) CHR A14 <- |06  35| <- CPU D3 (fr)
   (r) CHR A12 <- |07  34| <- CPU D2 (fr)
 (f) CIRAM A10 <- |08  33| <- CPU D4 (fr)
   (r) CHR A15 <- |09  32| <- CPU D1 (fr)
   (r) CHR A17 <- |10  31| <- CPU D5 (fr)
      (f) /IRQ -> |11  30| <- CPU D0 (fr)
   (f) /ROMSEL <- |12  29| <- CPU D6 (fr)
       (f) R/W -> |13  28| <- CPU A0 (fr)
   (r) PRG A15 <- |14  27| <- CPU D7 (fr)
   (r) PRG A13 <- |15  26| -> PRG RAM /CE (w) ?
   (f) CPU A14 -> |16  25| <- M2 (f)
   (r) PRG A16 <- |17  24| -> PRG /CE (r)
   (r) PRG A14 <- |18  23| ??
   (r) PRG A18 <- |19  22| -> PRG A17 (r)
           GND -- |20  21| <- CPU A13 (f)
                  '------'             

ps.: Pinout VERY similar to OEM MMC3.

    PRG RAM pins needs confirmation.
