Sprite overflow games

The following is a list of games which rely on putting more than 8 sprites on a scanline.

Use of sprite overflow flag

The sprite overflow flag is rarely used, mainly due to bugs when exactly 8 sprites are present on a scanline. No games rely on the buggy behavior. See sprite overflow bug for more details.

Nonetheless, games can intentionally place 9 or more sprites in a scanline to trigger the overflow flag consistently, as long as no previous scanlines have exactly 8 sprites.

Commercial

• Bee 52: At the title screen, the game splits the screen with sprite overflow (at scanline 165), then splits the screen with a sprite 0 hit (at scanline 207). If sprite overflow is not emulated, the game will crash at a solid blue-purple screen.

Homebrew

• blargg's sprite overflow test ROMs: tests behavior of sprite overflow, including the buggy behavior.

Use of excess sprites for masking effects

Some games intentionally place multiple blank sprites early in the OAM at the same Y position so that other sprites on those scanlines are hidden.

Commercial

• Castlevania II: Simon's Quest (a.k.a. Dracula 2): when Simon enters a swamp, the lower half of his body should be "hidden".
• Felix the Cat: when entering or exiting a bag.
• Gimmick!: when entering a level.
• Gremlins 2 - The New Batch: uses multiple blank sprites to mask rows during cutscenes.
• Majou Densetsu II: Daimashikyou Galious: when entering a doorway, Popolon's body should gradually disappear (to imitate walking down stairs); Youtube video demonstrating the effect.
• Ninja Gaiden: some cutscenes (more details needed).
• The Legend of Zelda (a.k.a. Zelda 1, Zeruda no Densetsu): when entering vertical (top-bottom-facing) doorways.

Misc

Commercial

• Solstice: during the intro cutscene, there are stray sprites on the screen beyond the 8 per scanline, but the NES won't display the excess sprites. This is not a masking effect, it is merely the hardware covering up a mistake that wasn't caught by the original programmers.
