I have Shadow over Mystara and Tower of Doom working on lr-fba-next on my rpi2. According to the compatability list, they also work in lr-mame2003 (https://docs.google.com/spreadsheets/d/1LP1MELCvcxu7TfiowF_0ZuvRVEMqlfQyTVetnOJvuJc/edit?usp=sharing).

I suggest you search by rom name, ddsom and ddtod, rather than game title.
