I'll try it at free time. It's doesn't boot in general or in game reboot/error/freeze/etc?
If not boot, it's restart console or just black screen?

It works in dma 16 or 8 reads emulated(default settings), but not in "true". I figured out it after i posted question.
It works almost perfectly that way(and i'm really nitpicking here). You won't get better experience anywhere(loading times are a lot better than best rips out there).

just goes black screen, or console reboots.
in ds4rc4.used default 4rc4 ide options(fast boot, auto system(where choosing: katana, hmb, wince), dma true, etc.

b- goes black(console hags up).
r- reboots consoleTrue dma don't work. It works in dma 16 or 8(didn't try others) reads emulated.
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?

Seaman works for me very good with true async DMA.
Shenmue 1 yes, still doesn't boot...

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.
