Is it about the minimal OS emulation that provides the UAE? In case you don't have the ROM file, you can always try without it (it can read the bootblock code and startup a game).
Maybe the 1.0 WB is minimaly tied to the ROM (I don't have a clue)?!
I've just read the post more carefully! You put the kickstart disk! That's how boots the ROM an A1000 :-)
