(re: Best MT32 emulator?) The DOSBox release referred to in the last post can to be found here. The driver mentioned on the site is older than the DOSBox capability but both work so you can try either. DOSBox needs a hefty CPU for protected mode games and this is even more so when you want to run the MT32 emulator.
You’ll have to ‘find’ the MT32 ROM image yourself as no-one is allowed to distribute it. Like Sierra, Roland is protective of its old technology.
