SD Gundam G Generation Over World - NPJH50681

I suppose this game's are locked in 30 FPS?

Depends. If you use "Only GE graphics (not recommended for homebrew)" it will lock your FPS at 30, while it will be 100% game speed. If you turn off "Only Ge graphics", and switch to "Save GE screen to Textures instead of Memory", you'll get the same image quality with the potential to get 90 FPS in the same time. At least it works that way in Overworld.
I'd assume that you should use the option that works the best for you.
