Heya Val!
Yep, I'm actually coming off my "hiatus" soon to take on those last two DS Zeldas.
That was a lot of the main reason I did my marathon. It started out with me wanting to give
MM another chance. Then I wanted to attempt a no-game over run of Zelda II. Then Zelda 1. Then I said, aw hell, I'll just play them all one after the other since I've never run them like that before. xD
Now as for the Four Swords games, the original
FS (that comes with LttP on GBA) is multiplayer only, which is quite frustrating--thankfully I was able to find someone to play it with.
But FSA--on GameCube--does have a single-player option, so you should be able to play that one.
You'll have to let me know how these games go.
