Any emulator works with standardformatted discs made by TOS 1.04 and up should work.
You can read more about this problem at

page 24 & 27.
Otherwise:
Try Tosbox
http://www.geocities.com/tosbox/
still one of the best emulators for using and making applications.
It is discontinued, like most emulators in (to bad).
Tosbox isn't great with games, so i hope you are using applications.
