I'm very happy to see Realm of Memories as a category for Four Swords. I had more fun running those levels than the actual main game (mainly due to them being more consistent). I always meant to come back to these to try for super fast time in all 3 levels, but I never did get as fast as I would've liked. I hope someone else gets super fast time on these levels as I find them fun and interesting. I have a recording of my Link's Awakening run, but I never did record my ALttP or LoZ levels (I think I did record them, but didn't keep the footage as I always wanted a faster time recorded). I do have my times saved for them though, as a reference for anyone who would like to beat them. ALttP (door 1 I think): 11:56 LA (door 2): 6:54 LoZ (door 3): 8:56
All these times, as far as I can remember, can be beaten. I did these in 2014, so I can't remember too much about them, but the fact I wanted to do better for them makes me think there's over 15-30 seconds in each one. I'm surprised I ever kept LA video since I didn't for the other two.
Overall, as stated above, I'm happy to see these added and I hope someone brings them all down to a very fast time.
Glad to help :) . I'll keep on grinding them! If you have any strategies, tactics, etc. you remember using I'm all ears. I found a couple of skippable rooms on door three-stage three for starts.
