I’m not sure if it’s lost media or just unavailable media, but there’s this game/story called Masks on this online educational service called IStation that I played in fifth grade I’ve been looking for, for a while.
its avalible media, if you have access to a reading istation account, you can go to the menu press iPractice go to 6-12 reading open timeless tales and press the hero's journey ( the thumbnail should look like the picture i linked idk if it showed up as of typing this.) and it should work. an istation account for one user is about 30$ so not exactly that much but still a good amount of money. (or be like how i was and ask my friends for their login to play it 💀 💀)
I will swear to my GUTS that I saw a video of some Crash Bandicoot homebrew on the Gameboy. It's not one of those bootleg games nor was it on GBC or GBA, this was apparently a fanmade demake of the original 1996 Crash Bandicoot game to the original Gameboy. It looked like crap & the music sounded empty, but it looked quite impressive nonetheless!
The homebrew also had a credits screen that was shown in the video after the boss fight(in which case I believe it was Cortex in some small spaceship) was defeated, but I sadly didn't pay attention to that & thus finding it again will be near impossible. Not like I would've remembered it all these years after only seeing it once & the video just never showing up again. It might've been a very low viewcount(less than 500 views?) video, but I can't remember the exact viewcount.
There's some iso files on Internet Archive that have a bunch of old homebrews from stuff like the Bung programming competitions. Emulez is one I know for sure has GB/GBC stuff. Maybe you could try searching those for leads
