Here's a minipack of mine containing some more Game Boy covers (along with improved versions of some preexisting covers because I'm a real freak about image quality):
Flash Gordon's Minipack
The Final Fantasy Legend
Final Fantasy Legend II
Final Fantasy Legend III
Kirby's Dream Land
Kirby's Dream Land 2
Legend of Zelda: Link's Awakening DX
Legend of Zelda: Oracle of Ages
Legend of Zelda: Oracle of Seasons
Lufia: The Legend Returns
I'm also taking cover requests (through PM so as to not spam up this thread). I'll deliver them privately until I can rack up around 20 different games, at which point I'll release it publicly as another minipack.
I enjoy taking seconds out of my day for total strangers.
EDIT2: Note to self (and possibly others): Must be under 40 characters, Must be png. Fixed once and for all, I hope.
