All Pixels Turn Black After Moving Sprite

[wezleysherman]

Hello! I have this compiled and running on my system (actually compiled it for an STM32H7!!)

I'm not sure if it's the STM or the emulator at this point, but Mario seems to be loading and working with the initial update. Then once the game starts playing it's like the background layer isn't being refreshed. As the sprite is moving on the screen everything begins to completely turn black.

Is there something wrong with the emulator?
