Tested in real hardware, played the whole game and everything worked just fine, beautiful port by the way, but sometimes one or two sprites get corrupted. As i could notice, it seens to be just one frame of animation when it is on an animated objetc, other times is a droped item, some scrolling background, the weapon projectile sprites or a HUD element. Almost always is just one sprite that gets corrupted in the scene and it shows as a whitebox or garbage lines with the size of the sprite. Most of the time pausing and unpausing the game solves the problem, but not rarely a new sprite gets corrupted. Entering again a room or scene when theres a door available also fixes the corrupted sprites.
