As you know there will be no more option "grab vram" in b47 and futher updates.

This PRX will be useful if you wanna take a screenshot of "real screen".

So you can use it with FuSa instead of grabvram+RVV.

UPDATED:
-You can also assign your own button or buttons combo with help of ConfiguratoR (Win32 version included in this package)
-Picture will be saved in the "PICTURE" folder
