About

The MMC5 contains two pulse wave channels that are identical to the internal pulse channels, except that the two hardware sweep units are missing. These channels also have a hardware volume envelope, accesible with Exx effects.

The MMC5 has an 8-bit DAC for PCM playback, which is not supported in Famitracker. Playing samples through the MMC5 DAC ($5011) or the 7-bit DPCM DAC ($4011) requires constant attention from the emulated CPU core. This isn't practical with the current FamiTracker NSF driver or most drivers used in games. A driver and hardware setup tailored for PCM playback is required.

A notable game using the MMC5 is Just Breed. A game which utilized the PCM channel is Shin 4-Nin Uchi Mahjong.

Check 2A03 for more details about the square channels.


Instruments

Due to the MMC5's pulse channels being a near clone of the 2A03 pulses, the instruments used by MMC5 are shared with 2A03. See 2A03 instruments.
