Readme

This utility helps in making maps of the levels in all those classic games. Eventually, it will be the digital equivalent of a player's guide with all the secrets revealed. For now though, it displays the frozen scene of a ZSNES savestate, exports the scene without HDMA effects or mode 7 distortion, exports VRAM graphics, and 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. 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.

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.
