A quick check of MAWS shows changes in 115u1-
WIP -0.115u1: Mathis Rosenhauer moved Atari vector PROMs into separate regions. Added user2 rom (036174.01) and the user3 Mathbox PROMs (36175/76, 036177/78, 036179/80 - low/high nibbled). Changed region proms to user1.
Not sure of the solution, but you either need to CMP your roms, use an older version of mame (perhaps just for that one game), or obtain the new? roms.
