I am admittedly low on the learning curve for my understanding of all things IT related. Ive built machines for emulating tho. And depending on what the hardware is, ive downloaded shadder caches for certain cases to improve performance. My very loose understanding of it is they are universal when certain things match like emulator and version. Are they being included in some roms/emulators and i just didnt realize or is there a more technical reason they arent included?
