Inputs are read from registers starting from r0 and outputs are written back to the same registers (also starting with r0).

ID	Name	Inputs	Outputs
0x01	ControlMemory	`r0`: `MemoryOperation operation` `r1`: `u32/void* addr0` `r2`: `u32/void* addr1` `r3`: `u32 size` `r4`: `MemoryPermission permissions`	`r0`: `Result` `r1`: `u32/void* addr_out`

0x03	ExitProcess	None	None, doesn't return
0x04	GetProcessAffinityMask	`r0`: `[out] u8* affinitymask` `r1`: `Handle process` `r2`: `s32 processorcount`	`r0`: `Result`
0x05	SetProcessAffinityMask	`r0`: `Handle process` `r1`: `[in] const u8* affinitymask` `r2`: `s32 processorcount`	`r0`: `Result`
0x06	GetProcessIdealProcessor	`r1`?: `Handle process`	`r0`: `Result` `r1`: `s32 processorid` `r2`: Clobbered?
0x07	SetProcessIdealProcessor	`r0`: `Handle process` `r1`: `s32 processorid`	`r0`: `Result`
0x08	CreateThread	`r0`: `s32 thread_priority` `r1`: `ThreadFunc entrypoint` `r2`: `u32 arg` `r3`: `u32/void* stack_top` `r4`: `s32 processor_id`	`r0`: `Result` `r1`: `Handle thread_handle`
0x09	ExitThread	None	None, doesn't return
0x0A	SleepThread	`r0-r1`: `s64 nanoseconds`	None
0x0B	GetThreadPriority	`r0`: Ignored? `r1`: `Handle thread_handle`	`r0`: `Result` `r1`: `s32 thread_priority` `r2`: Clobbered?
0x0C	SetThreadPriority	`r0`: `Handle thread_handle` `r1`: `s32 thread_priority`	`r0`: `Result`
