A bit of a necro, but it sounds like it's referring to MMC5 raw PCM, which is definitely used by at least one official game (the Mahjong one, as I recall) and thus needs to be emulated.rainwarrior wrote:I don't know what would possess someone to use MMC5 PCM, other than utter novelty. It's redundant to the existing APU PCM feature, and poorly supported by emulators.
