Syscall index: 0x17E6
Function signature: void TakeScreenshot(void)
Screenshots the current VRAM contents and opens a dialog where the user can save the screenshot to a picture file, in the format specified in the Link menu (G3P or BMP), or discard the screenshot by exiting the dialog. This is the same behavior as when CAPTURE (Shift+7) is pressed while GetKey is running.\
The existence of parameters or return values is yet to be studied.
