Hey staff

when i tried to play pokemon studium 2 on both n64 cores on retroarch it did not work out that well

the screen flickered all the time and when i tried it out on the second n64 core, it just shows a while screen all day

I need some help please, i am having trouble putting new codes on my games because the code format on retroarch is very hard for me to understand
