FamicomHDL
I have made some of FamicomHDL already and I think the following code seems to work for implementing NROM-128 with vertical mirroring:
import Language.FamicomHDL;
import Language.FamicomHDL.Cartridge;
import Language.FamicomHDL.Memory;
nrom :: Mapper ();
nrom = do {
prgrom <- makeROM 0;
chrrom <- makeROM 16384;
connects $ zip cpuAddress (take 14 $ addressPins prgrom);
connects $ zip cpuData (dataPins prgrom);
connects $ zip ppuAddress (take 13 $ addressPins chrrom);
connects $ zip ppuData (dataPins chrrom);
connect romSelect (chipEnablePin prgrom);
connect ppuA13inv ciramEnable;
connect ciramA10 (ppuAddress !! 10);
connect (chipEnablePin chrrom) (ppuAddress !! 13);
};
Perhaps commands should be added for some of these things make shortcut. --Zzo38 22:38, 28 October 2012 (MDT)
