devkitPro

I am using bool SpriteEntry::hFlip to change the direction my sprite faces when the sprite
changes direction. When I run my program on an windows emulator (GoodNDS in this case)
my sprite changes direction like I want. But, when I load my program on my DS lite using
a MaxMediaDock CF, my sprite always faces the same direction. Am I doing something
wrong, or is it just my MMD?

Try a simpler program, like the enclosed devkitPro example Sprite_Bitmap to see what happens.
