====vu0====
====idle detect====
For JAK emu. Todo: Exec from VIF0 seems to always run program for 0x7FFFFFFF cycles...
 
void __fastcall Vu0MicroExec()
* --detect-idle-vif
{
* --detect-idle-ee
  run_vu0(vu0_functions_ptr, 256LL, 0LL);
* --detect-idle-iop
                                                // run vu for 256 cycles.
* --detect-idle-intc
                                                // This kill whole sync idea. We have 256 cycles run already on first run.
* --detect-idle-chcr
                                                // Games like SST/ARR/TM:HEAD-ON are alredy broken before we even started.
 
====other====
  if (is_vu0_running())                        // if still running (no ebit, no mbit)
 
  {
* --force-point-sampling
    v0 = ee_sched_stru;
* Project Snowblind US mipmap offset 0019506C  bc1f    loc_19508C
    v1 = 0LL;
 
    v2 = *(ee_core_regs_base + 0x378) - *(ee_core_regs_base + 0x370) + 512LL;
====vu====
                                                // passed cycles + 512
 
                                                // terrible idea, we are falling behind ee here.
Looks like VU sync always(?), not like ps2.
                                                // There is usually no point to run behind ee if we failed to do this at start.
                                                // This break games like Ratchet/Rayman.
    sched_Vu0MicroExec.delta = v2;
    if ( ee_sched_stru )
    {
      while ( 1 )
      {
        v3 = v0;
        if ( v0[2] >= v2 )                      // if delta from scheduler higher than from v0
          break;
        v0 = *v0;
        v1 = v3;
        if ( !*v3 )                             // schedule next run...
