Raphael is Link's best friend. He appears in his memories. He is the purple-haired guy killed by Thaneris in the ambush in the desert.
Indeed, Kentor was killed by Athel in the battle at the castle front. It's mentioned in the introduction of the game. The Hyrule Army lose because of Thaneris' intervention.
You must transfer all "Save" files to the "Data" folder of the updated version of the game. As a precaution, back up your original game files before making any moves.
Try downloading the game directly from its website "https://pezetagames.github.io/ZeldaToP/download.html". Running the file "Zelda ToP DX.exe" may cause Windows to activate the antivirus, but don't worry, just tell it to ignore it.
Maybe you are missing the key hidden in the sub floor. There is also a key in the room with the teleporters. Otherwise, I recommend you to look for some walkthough on youtube.
1º Complete Irma's side quest in Sirion (after you can move freely around Hyrule). If you're already in the last moments of the game, enter the snowpeak at the east exit of Sirion. At the end you will find a cave where you will find the ring.
2º Obtain the Champions Cup in Sirion (it's the last cup).
3º Complete the Skull Kid mission (Majora's Mask).
Ohhh thank you so much for your comments. Yes, it is true the game has several problems, but in general the reviews are rather positive. I really hope you enjoyed the game.
On a side note, I will be releasing a DLC for this game in a few more months. I recommend you to follow our networks to stay tuned (https://www.facebook.com/ZeldaToP).
