Most games support Adlib/FM for sound effects. If you look at it in this perspective, all games that do NOT mention that it supports "Sound Blaster Only" or "Sound Blaster Required" will have an option to choose the Adlib for sound effects.
Some common exaples :
1. Wing Commander I
2. Prince of Persia
3. Gods
4. Prehistorik
5. Zeliard
and many more...
Unless of course if you're asking about those games that ONLY use FM sounds for sound effects - which means all pre-Sound Blaster cards and those that don't use the MT-32's custom sound effects patches.
Also, many games, in spite of providing "Sound Blaster" as a choice to choose the sound effects, they still use the FM sounds for the effects. Most developers did this to make it easier for end-users at home, who may not know that the Sound Blaster has Ad-Lib compatibility, and for those to choose "what they had" installed in their systems.
