Hello, I'm new to Zelda Classic, but I happened upon the BS tileset version of the original first quest and have been enjoying playing it...however, it (the version I downloaded, at least) used the original NES sprites for certain things, like Dodongo (not sure why, it has a BS sprite), and Gleeok (which I understand was not in the BS game and thus has no sprite). So, I thought I'd try my hand at revising the original Gleeok sprite in BS style if it's of any interest to anyone.
For the most part I used Aquamentus' BS palette, and I even made a second version with an edit of the Aquamentus wings. I made two alternates for the head, since in almost all depictions (manual artwork, cartoon, etc), Gleeok has a single horn on its forehead rather than the two horns in the sprite.
Anyway, I haven't learned to use the editor yet, so I'm not sure how to edit this into the quest, but I thought I would share the sprite and see if anyone else might find it useful. 😊
