OutRun (Arcade)

OutRun is more or less a 1980s arcade driving experience unlike any other. It has multiple endings, a catchy soundtrack, and some nice scaling hardware. Oh, and you drive a Ferrari too. What more could one ask for?

Unused Text
Present at when the ROMs epr-10380b.133+epr-10382b.118 are interleaved is this text that may have been used in debugging. Error!

Mode=User

Unused Lap Timers
There is unused code for displaying the time used to reach a checkpoint. It can be used in the MAME debugger with the command d0 = X; pc = 7fea; g;, where X is the lap to display.

Unused Traffic Mode
There is unused code for having traffic flow toward the screen. It can be enabled in the MAME debugger with the command b@60b6b = 1, but the game lacks graphics for cars viewed from the front, so it looks like they're driving in reverse very quickly.

Developer Message
By setting the program counter to (by typing pc=0x7644) in MAME's debugger and resuming the game, this message will appear: It's likely just an error message. Bin(-chan) is Satoshi Mifune, one of the game's programmers and a frequent collaborator with Yu Suzuki (it is assumed Suzuki left this message). A similar message appears in Space Harrier.

Unused Graphics


Alternate graphics for the Start and Goal signs. In the final game, these are more cloth-like banners.

Unused Sound
A leftover sound from Space Harrier, which is supposed to be "VOICE 4" in the Sound Test but cannot be heard because it is in 4000 HZ.

Unused Map

An unused layout for Coconut Beach can be found within the game's code. This seems to be for testing purposes, as there are several different types of signs present. This level can be enabled through the MAME debugger with the command focus 0 bpset e4ea,1,{b@260010 = 3A; g} in Revision B.

Easter Egg
There's an Easter egg which causes the message to appear onscreen. However, the method of activating the message is different depending on the version:


 * Revision A - Just before any checkpoint, hold Start just before the sky is due to cycle to the upcoming level color.
 * Revision B - Achieve a high score and enter YU. (including the period), then hold Start while while transitioning from Stage 2 to 3. It should be noted that the message can only be displayed once and is then deactivated, along with being deactivated if the player enters "YU." again on the high score table.
