Yaiba: Ninja Gaiden Z [NPUB31256]

digitaldude and quick.sliver1, i will just said that or you have the pc of nasa or no sure whats you do to make that game run on 30 fps, i have a normal pc i5 and the maximun i normally get for it is around 15 fps or around  7 fps on some parts like on hayabusa scene. i havent test on the latest builds but i remenber that it was one of the slowest game that i test, even ultra street fighter 4 or street fighter x tekken goes full speed for me when it have even better graphic than yaiba.

Pidgey, you should realize by now emulation is majority about CPU core (GPU, shader cache are just an extra important features).
 
Using i5 for highly experimental emulator is a painfully stressful toward low-core CPU., unless you know how to diminish those stress (like tweaking CPU usage processes number).  FYI, CPU (@ 80 or less process) is an optimal choice for emulation under i5. Can be done by:

• Terminate/Stop redundant app services (permanently or temporary. Ur choices)
  
• Disable your unwanted startup app
  
• Remove Win10 Bloatware app
  

Afterward, you might be able to run playable-title smoothly with low-core CPU.  Otherwise, wait for developer team to optimize rpcs3 for low-core cpu.
