Cool! I just bought my Everdrive GB recently. Neat little device!
I've been studying Game Boy programming lately. I used RGBDS for my assembler, Notepad++ to edit my code, and the BGB emulator to test my ROM before moving it to my Everdrive. (BGB has some fantastic debugging tools, BTW.) I used this code as a starting point: https://eldred.fr/gb-asm-tutorial/hello-world.html. To create the tiles for the Atari logo, I used "Gameboy Tile Designer", a program that's starting show it's age, but it's still useful.
If anyone is interesting in learning Game Boy programming or understanding some of the technical details of the Game Boy, I recommend this video: https://media.ccc.de/v/33c3-8029-the_ultimate_game_boy_talk
