You could actually play the GBA ones or the DS ones on emulators, the controls for the GBA emulator are actually pretty good, I haven't used the DS one.
If you're on android then download the emulators here:

I don't know about iOS but I'm sure they'll have similar apps.
You can get the ROMs for free from certain sites if you google them. Either download them directly to your phone or to your PC and then transfer them to your phone.
I played FoMT during one of my lectures (they were boring) a few years ago using this and connecting a wiimote to my phone.
This is what I use on Android - https://play.google.com/store/apps/details?id=com.gemuvn.gba
