None of the examples work. Only white screen.

Hello Everyone! I'm new to devkitARM and I have a strange issue.
I used the installer to setup devkitARM on Windows and used msys2 to compile every single example. They all compile successfully, but when I try to play them on DeSmuME, nothing happens. The emulator stays in an eternal white screen.
At first I thought it was a problem with the emulator but other games work fine. What am I missing here?
