Ring Transfer Trick:

This code requires Legend of Zelda: Oracle of Ages and Legend of Zelda: 
Oracle of Seasons.
I got the Rang Ring L-1 and L-2(makes boomerang damage go up) with this 
trick. I also got the Sign Ring AND THE L-1,L-2,L-3 POWER RING(Make 
Your 
Damage Go Up) with this trick
First, go to Vasu’s Jewelry store and ask the red snake(right of Vasu) 
the 
secret(doesn’t matter which game your on). Write down the secret. Then 
play 
the OTHER game and choose SAY SECRET(it might say SAY SECRET) to the 
red 
snake(right of Vasu)and press OK. Then he’ll say he transferred the 
rings. 
Talk to him again and choose SAY SECRET again(it might say SAY) the 
password 
you just put there will still be there. Change the last 2 or 3 or the 
secret(doesn’t matter what you change it to) and it might be another 
secret. 
If it says wrong, change again. Just repeat.
