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.
