Depends as not all games utilize it. Sometimes it holds a duplicate of the VRAM, sometimes nothing, and some games use it as a back-burner (like a stove) of sorts.
For example, Contra III only loads a frame for current pose/s (since it is a two player game) in the VRAM for the player. In the WRAM, it loads most of the character's sprites (not the Mode 7, but it does load the bike sprites) and uses these for the VRAM instead of loading directly from the ROM. You'd have to check to see if it loads anything for a game, sometimes you get lucky.
