Make sure you change the background colour black for exactly the mode 7 tile palette, or else your changes won't have an effect.

It comes in handy if your bg within the MemViewer is clashing with the mode 7 tiles. Still PalViewer: Within the corresponding tileset palette, you should click on the first colour bar, which is responsible for the background colour, to change it. In SMW, you can see it when you open the PalViewer within vSNES, it's the first row (7 colours excluding bg colour) The mode 7 object should have the correct palette from the start. Make a quicksave in ZSNES with the mode 7 object you want the tiles from General Ripping for Mode 7 Object Tilesets (SNES) Note: Every mode 7 frame needs one quicksave in ZSNES to be viewed in vSNES. Use it to save the picture with the mode 7 object. Below the options for transparecy, you should see a floppy disk symbol. Choose a non-clashing colour from the given colour palette. 0 gets unchecked that way) and click on the colour bar right next to it. 0 is probably checked, but we want a different bg colour.

If colours are conflicting (like a black outline of the mode 7 object on black background), go to SceneViewer-layers-Mode7 backgrounds and then look at the lower right of the window at the area with the options for transparency. Here you should see the mode 7 frame in its unresized and non-rotated form. Within vSNES, open the SceneViewer and go to layers and then to Mode7 backgrounds Make a quicksave in ZSNES with the frame you want to capture General Ripping for Mode 7 Objects seen in Gameplay (SNES)
