Hack: “No Ads” Patch

During gameplay, small text “advertisements” keep appearing randomly on screen that read “Nintendo Virtual Boy”, “T&E Soft Presents” or “Redalarm”. If your system is low on power, the text “Batteries Low” will also appear. This patch removes all of those messages except the latter.
