In fMSX the NTSC/PAL switch does not work, the games will run at 60hz but not 50hz. And if you’re wondering why I don’t just use the bluemsx core it because it does not support save states. The reason I want 50hz is because on windows I use the stand alone bluemsx.exe and it defaults to 50hz so without even realizing it I was hearing the games the way it would sound in pal regions. Now I’m so use to the why they sound at 50hz that when playing on my android it just sounds wrong like the music is playing too fast.
