Bluemsx SCC #6

Open roo1234 opened 3 months ago

Konami sound chip SCC games are slow and broken audio. For MSX1 and MSX2 games, like Kings Valley 2.

Seems like the SF2000 struggles with some audio processing (the Fake08 core is also a good example).

More information on SCC, as it only affects certain games, which are listed here: https://www.msxblue.com/manual/scc.htm

Even if it worked better, the sound will still be mono on the SF2000. But perhaps there would be a way for someone to optimize the code. (Leaving this open.)

it would be nice to add an option to disable SCC, so the game would play fine, but missing audio channels. Perhaps this is too embedded in the core, the extra SCC audio should skip processing, disabling SCC completely
