Well, i need take a time to make a custom ntoskrnl_emu for One-Core-API, because the main not working. It's occours because ntoskrnl_emu use a method to get address from some internal functions on kernel and as one-core-api use a custom kernel, the address are different. And, i tried transplant ntoskrnl_emu functions to one-core-api kernel and drivers (like USB 3.0) not working. I need time to investigate.
