Hang-On is a motorcycle game notable for being the first "full body experience" game, featuring a rideable bike-shaped cabinet, as well as being one of the first 16-bit games with (pseudo) sprite scaling. So, you know. Pretty important developments.

Unused Graphics

You know what this is
The standard SEGA logo, likely used before the fancy sprite-based logo was put into the game.

Stop yelling at me!
An older version of the game's logo, found in pieces throughout the background graphics ROM. Again, this BG-based logo was replaced with a sprited one that showcases the game's pseudo-scaling features.

How very interezzzzzz bing bing bing
An older, simpler game map, with progress markers for every possible curve and straight section on the map.

No cactus, no problem

Location markers that would have been used on the old map. Notice that there are only four stage numbers and four pieces of scenery (besides the Start and Goal banners). It's possible that the desert stage wasn't part of the game when these markers were drawn.

World's fastest race

These markers were meant to be used on the final game map. They were likely dropped in favor of the more impressive cyclist background.

Old Final
OH NO! OLD GOAL!? Still not big enough!

The third, and thankfully last, "GOAL" graphic. This background graphic was replaced with a much larger sprite.

Unused Music

The last 3 seconds of the ending track are usually cut off by a jump to the high score screen.
