SMB1's GFX aren't compressed, you don't need to extract them. Well, unless you mean porting GFX from one ROM to another, in that case, just open up two windows and use the copy and paste tools to transfer the graphics to the other ROM.

SMB Utility has the ability to insert GFX from other SMB1 roms. If a SMB1 hack has existing edited CHR graphics (not including TSA arrangements), then you use that option to copy it.
