The game is already too easy and you even have easy difficulty.
If you want to make it even more easier but not affect the game too much,you can use my codes(I create a save at the first save location with those codes and with them the game is still nice to play)

Have All Magic(except Eset Button and Heart's Prison) - I don't use this on that save but I enable it at the end of the game.
Remove Eset Button magic and add Reset Button Magic - I use this code on that save and enable it again once I get the Eset Button song...I like the Reset Button Magic because I can test things without having to start another battle and the Eset button sometimes fails
Have all Skills(Attacks) - I prefer to have all the attacks at the beginning of the game(I already clear it at least 5 times)...this code makes the game easier
Have all 100 I.P.Ds in the fan club - I enable this code at the end of the game
Have only Eipp,Kasha,Blanca and Oryu - those girls are on that save and already set(don't remove them until you get the ability to use them)...personally I think those are the best of all(this code also makes the game easier because it allows you to hit perfect more easily)
Max Leaf - collecting money to get something on a game that you cleared so many times is boring so this is enabled on that save
All of the codes can be disabled once they are applied,they don't need to be always enabled to work(except the last one)
