Hi everyone,
I'm working on an NES emulator, and the PPU I wrote looks good. However, I found one strange behavior when playing the Super Mario Bros. i found the mushroom, which is supposed to gradually appear on the screen, is actually drawn on the screen entire from the very beginning, and then the entire mushroom sprite moving up. I guess I miss something here for the emulation. Does anyone know what's wrong with this rendering? By the way, to handle the sprite priority, I'm actually drawing from the last sprite to the first sprite (sprite No.63 to Sprite No.0). Please help. Thanks!
Regards,
Charlie
