This utility helps in making maps of the levels in SNES games by displaying the frozen scene of a ZSNES savestate:

• Displays the plain backgrounds, without distracting sprites or effects like HDMA or mode 7 distortion
• Exports the scene to a bitmap file
• Displays VRAM graphics
• Tells technical info about the registers

There are a few cases where the scene is not displayed correctly, not because of a flaw in the rendering, but because certain games split the screen into different sections (HDMA effects). Since BgMapper is not an emulator and only shows the frozen state, it displays just the section of the frame for when the state was saved, meaning that if the game changed the video mode halfway through displaying the frame, you'll only see half of the screen correctly.

BgMapper .177 - minor change

• Added command line parameter to force a desired SNES video mode '-fv #'. Someone was at wit's end trying to view savestates from SD3 during the map screen because it never showed it in mode 7 - never. I can't figure out what SD3 is doing either because it seems like no matter when the state is saved, the video mode register is ALWAYS 1 - regardless of what scanline or cycle it is saved on. So, I just cheated by forcing it to mode 7, "-fv 7". (credit A.Lurker)
• Recompiled to PE format rather than RDOFF - no real significance, just a note. It's still a DOS program after all.
