Difference between Links Awakening and the DX Version?

So, there are a few differences between Link's Awakening and Link's Awakening DX

Legend of Zelda - Link's Awakening was originally released for the Game Boy on June 6th, 1993 (August of 1993 in the USA). It featured our normal camera top view and our favorite Protagonist, Link. You were tasked with adventuring all around Koholint Island, gathering 8 Siren instruments. As you gather everything and you defeat the bosses (named Nightmare), you start to learn more about the Island and how it came to be. Once you gather all 8 Siren Instruments, you are to adventure to the top of Tal Tal Heights and use them to open a pathway into the Wind Fish's egg, where the Wind Fish slumbers. After you traverse this final dungeon, you defeat the final nightmare and you finally awaken the Wind Fish. He is grateful that you have awakened him, then tells you that it's time for you to wake up. Once you actually wake up, you realize that the Island of Koholint never existed.

Legend of Zelda - Link's Awakening DX was officially released for the Game Boy Color on December 12th, 1998 (December 15th, 1998 in the USA). The same story, same bosses, and same Island of Koholint are back again. This time, they were in glorious color. However, there were a few new additions that were added to the main base game. First and foremost, color. Game Boy Color featured this game in full color this time, rather than the grey scale we were used to on the original. Introduced with the Game Boy Color, was the Game Boy Printer. This Printer was able to be combined with the Game Boy Camera, and you could take pictures. Basically, it was Nintendo's way of starting the Selfie Era. However, it was used in Link's Awakening DX to print pictures that you took with the DX Camera Box from the Camera Shop. One of the best features it brought to us was the Color Dungeon. This new dungeon was able to be found on the Island of Koholint. It featured very unique enemies and a useful item at the end. After to completed the dungeon, you were given a choice of either the Red Tunic or the Blue Tunic. Red Tunic gave you more attack power permanently. Blue Tunic gave you more defense power permanently. Once the dungeon was completed, it disappears from the Island.

It's also worth mentioning that the original had you collecting Stone Tablets for dungeon hints, but in the DX version you find Stone Beaks and have to place them on Owl Statues for hints.
