Mixed samples are stored in a large enough (at least n) 32 bit buffer pointed by b. This buffer have to be previously filled with the YM-2149 samples. Typically it is the YM-2149 emulator output buffer. This allows Micro-Wire emulator to honnor the LMC mixer mode.iven LMC mode. This porocess include the mono to stereo expansion. The mem68 starting pointer locates the 68K memory buffer where samples are stored to allow DMA fetch emulation.<p>
