vu0[edit source]
For JAK emu. Todo: Exec from VIF0 seems to always run program for 0x7FFFFFFF cycles...
void __fastcall Vu0MicroExec()
{
run_vu0(vu0_functions_ptr, 256LL, 0LL);
// run vu for 256 cycles.
// This kill whole sync idea. We have 256 cycles run already on first run.
// Games like SST/ARR/TM:HEAD-ON are alredy broken before we even started.
if (is_vu0_running()) // if still running (no ebit, no mbit)
{
v0 = ee_sched_stru;
v1 = 0LL;
v2 = *(ee_core_regs_base + 0x378) - *(ee_core_regs_base + 0x370) + 512LL;
// passed cycles + 512
// terrible idea, we are falling behind ee here.
// 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...

seems to be like internal threads, not real threads. Emu print with that.
