Hi-Resolution and Interlacing

PPU Register $2133 SETINI can enable hi-resolution mode, allowing a 512-pixel horizontal resolution. This causes every even column to display the main screen, and every odd column to display the sub screen. Outside of mode 5, this is usually used as a way to do a 50% blend of the main and sub screens (a.k.a. "pseudo hi-res"). Under composite, this resulting blend can look somewhat smooth, but through S-Video or RGB the vertical stripes might be clearly visible.

In Mode 5, hi-resolution is automatically forced, and the main and subscreen are automatically overridden with alternating columns of the BG layers, allowing an effective double-width resolution.

PPU Register $2133 SETINI can enable interlacing, causing the scanlines of every second frame (field) to be offset downward by half a line. In mode 5 this allows an effective double-height resolution.

Game	Notes
Syvalion	Mode 5 and interlacing for high resolution text screens at the beginning of the game.
Seiken Densetsu 3	Mode 5 for text boxes and menu screens for a higher resolution Japanese text rendering.
Rudra no Hihou	Mode 5 for text boxes and menu screens for a higher resolution Japanese text rendering.
Desert Fighter / Air Strike Patrol	Mode 5 and interlacing for high resolution mission briefing text.
Radical Psycho Machine Racing (a.k.a. RPM Racing)	Mode 5 and interlacing for high resolution graphics throughout the game. The Japanese release replaced the high-resolution gameplay with low-resolution mode instead.
Jurassic Park	The HUD overlay and a notification box during gameplay uses pseudo hi-res for a transparency effect.
Kirby's Dream Land 3	Uses pseudo hi-res for a foreground transparency effect.
PPU Bus Activity Demo	Demo by lidnariq which includes mode 6, among other things.

Overscan (239 lines)

PPU Register $2133 SETINI can choose either 224 or 239 lines of visible picture. Most games used 224, allowing a significantly longer vblank period, and the extra lines weren't normally visible on contemporary NTSC televisions.

Game	Notes
Rendering Ranger R2	NTSC (Japan), often manually blanks several lines at the bottom.
Super Mario All-Stars	PAL version only.
Super Mario Kart	PAL version only, but with some "manual" letterboxing.
Super Mario World	The launch PAL release did not use overscan, but a later PAL revision did.
Super Tetris 2 + Bombliss	NTSC (Japan).
Super Tetris 3	NTSC (Japan).
Tetris & Dr. Mario	Both NTSC and PAL versions used the overscan area.
Tom & Jerry	NTSC and PAL.
Yoshi's Cookie	NTSC and PAL.

Vertical Offset-per-tile

See: Offset-per-tile

Game	Notes
Tetris Attack	Used for independently shifting columns of gameplay.
Timecop	During the introduction, used for a wobbling effect on the time machine.
Yoshi's Island	Used for the 1-7 "Touch Fuzzy Get Dizzy" effect, and moving platforms in 6-4 "Tap-Tap The Red Nose's Fort".
Bust-a-Move / Puzzle Bobble	Used to make the playfield shift downwards without affecting the fixed frame at the sides. This game also uses background mode 4.

Prehistorik Man	Used on stage 21 (Icebergs) to simulate rotation on the ice platforms.
Aladdin	Used on the final boss fight.
Axelay	Used for large vertically moving obstacles on the second level.
Battletoads in Battlemaniacs	Used for a wavy effect on a flag in the game's intro.
Super Turrican 2	Used in the fourth area of the first level.

Horizontal Offset-per-tile

The horizontal version of offset-per-tile is especially rare, since scanline horizontal scroll changes can already do a smooth horizontal offset, and this hardware feature only provides a coarse one.

Game	Notes
Chrono Trigger	During the introduction, this is used for a "shimmering" effect on the Black Omen ship: video
Super Genjin 2	Used for a screen transition effect on the title screen, when the intro animation isn't skipped. Uses mode 4.
Super Mario All-Stars	Used in Super Mario Bros 2, for a screen transition between title screen and character select.

Direct Color

See: Direct color

Game	Notes
Actraiser 2	The mode 7 overworld map uses direct color.
Aerobiz	The title screen uses mode 7 direct color.
Romance of the Three Kingdoms II	The title screen and introduction sequence uses mode 7 direct color.
Secret of Mana	The spherical world map uses mode 7 direct color. The flat world map uses mode 3 direct color. While riding Flammie, press Start for the spherical map, then press R to switch to the flat map.

Mode 0

Mode 0 is somewhat uncommon, but provides 4 independent layers of 2bpp graphics.

Game	Notes
Super Mario Kart	For the layered "Choose your driver...." screen with separately scrolling text and ground.

Game	Notes

Mode 4 8bpp

Mode 4 provides 8bpp graphics on BG1 with offset-per-tile.

Game	Notes
Bust-a-Move / Puzzle Bobble	8bpp graphics are needed so that all combinations of adjacent bubble colours can be accomodated on the tilemap. Also uses OPT to shift the playfield.

Mode 7 EXTBG

While Mode 7 was very popular, Mode 7 EXTBG was not very common.

Game	Notes
Super Ghouls 'n Ghosts	Used to put the level over the player's feet on a rotating level.
