I would like to change the part in the above picture that says "A LINK TO THE PAST" to "ZELDA'S QUEST" if possible.
Your best bet would be to use the program from RHDN to decompress the Graphix open the Graphix file with YYChar make changes and then reinsert them back into the game with your changes,
the program is self explanatory in it's readme I just did it and I've never hacked a SNES games graphix's before.
Just don't put anything over THE "THE" part "Because it is Mirrored" like I did at first you just have to remove it or at least I did.

Another tip is instead of naming the uncompressed part .Bin name it .SMC makes it easier for editing in Yychr.
You have to use the command line but this works for windows 7 just create two separate .Bat files.
Extract or Well decompress
zcompress 0 Zelda.smc Graphix1.smc
zcompress 1 87200 zelda.smc Graphix2.smc
if you noticed I renamed it after having edited it with YYchr.
