I select Dma then change "true" to 16. Do i disable dma by changing "true" to "16"? How it's different if i would choose "emulate 16", but would not turn on dma in options?

DMA disabled only if you uncheck DMA checkbox.
Emulate async and true async uses DMA if you checked DMA. True async can't works without DMA, but emu async can.

True async read data clusters by interrupts and it's works faster and most natively than emu async.
Emu async read parts (and clusters) of data every video frame and it's blocks context while reading a part.
True async doesn't blocks context, the reading going in background process by hardware.
