I’m using ParaLLEl and loving it. I was using mupen64plus because the 16:9 option was awesome, instead of stretching the image it would just “open the screen” showing more stuff, best option ever and parallel widescreen option sux ass because it stretches the picture.
But I choose ParaLLel because my games runs faster with it and there is an option to run games on fullspeed and I think that option unlocks the 30fps limit from some games (anyone correct me if i’m wrong), Zelda, Goldeneye and Perfect Dark are running full speed 60fps here and that option alone made me choose parallel core.
