Well, the usual goes, but what are the specs of your computer? I can say from experience, however, that the "Roland" option actually is one of the few instances where you need a Roland CM-32L or CM-64. Most of the time for the older games, the "Roland" option is for the MT-32 (and not all MT-32 games would work with a Sound Canvas, due to patch programming). Some, however as mentioned, used the two CM modules which had extra sound effects.
Back on topic, can you post the specs of the machine you're running it on as well as your config.sys and autoexec.bat files? I'm not AS knowledgeable or experienced as some in here, but for helping someone enjoy such a great arcade port I wanna do what I can.
