Ocarina of Time never natively supported any aspect ratio other than 4:3, so it will certainly be stretched. Unless OP plays on an emulator or the native PC port, which can both support 16:9.
How did you get the master sword without finishing Jabu Jabu? Normally you would need all three spiritual stones to get inside the temple of time where the master sword is.
One of the best games ever. Try completing it with only 3 hearts and no deaths ;) Back in the day you could get your name published in Nintendo Power for accomplishing that feat.
The N64 was the only Nintendo console I skipped. I just couldn’t afford two consoles and the PlayStation was obviously a better choice, but I still kinda wish I had gotten to experience Ocarina and Majora's Mask when they were brand new and not years later on the GameCube. I played at my friend's houses, but just hated that controller. The Wavebird made it a bit more palatable, but it was still just too "avante garde" for its own good. Feels like I needed yo shove a mop handle in the expansion port and use it as a trident.
I don't know why but I always get stuck around the spirit temple and have to look up wtf to do. This has happened every playthrough and you'd think I'd remember it. Good luck!
