Getting there...

The 'copy save' menu is not finished yet, which is I didn't show that off. The copy menu is effectively the 'erase save' menu, but with a flag set to copy data instead of erasing it (also a title bar change so you know what menu you're on).
Awesome work, DarkSamus! That menu is 1000x better than the original.

Here is another little thing that could be fixed. On the title screen, there is a star in the sky that overlaps with the game logo. This isn't normal behavior for stars in the sky. This odd star is actually grouped together with stars in the ocean. An odd little bug that is probably unknown.

Changing its sprite priority doesn't place it behind the logo, much like the other stars in the ocean. I believe they have this unique behavior because they are supposed to appear over the tiles in the ocean, which is a different background layer than the sky.
At 0x168C9, this is the data for this star. If you change the 78 to 90, it will place this star in ocean to be with its other fellow stars. This would be the most minor of changes, but I thought some people might like to know this little bit of info.
Edit:There is an error in the title screen text. There is no space between the "," and the word "CRYSTALS".
"TO BREAK THE SEAL,CRYSTALS"
Edit:In the bank used for town gfx, the "," to the left of the "?" tile should be blank. Random commas appear in dialog when talking to NPCs. This one is my fault. I accidentally placed it there when adding that smaller font. Sorry about that!
Edit:I have a question about Bagu's (Bug's) new text. He says:
"Show this letter to the ferry landing man", so is this more closely in line with the japanese version? It doesn't really make sense, as there is no indication that the game has a ferry landing - except maybe at Mido, but at this point in the game you wouldn't know about Mido. I'd suggest something like
"Show this letter to a guard at Saria Bridge." I tested it to make sure it would fit, and you'd need to repoint the line of text to fit the 3 extra characters. Anyway, makes a lot more sense.
Edit:Link now has a Blue and Red tunic! Upon using the Shield spell with a Defense level between 1-4, you'll get the Blue tunic. Once you get up to level 5-8 of Defense, you will get the Red tunic
Another bug report: In your current version, it's set to check Link's sword level, not defense level.
