Arkanoid (Arcade)

The mothership Arkanoid was attacked by unknown forces. The spacecraft "Vaus", armed only with an elastic orb and rubbery armor, must destroy rectangular tiles and battle against Homer Simpson's catchphrase.

Stage Editor


A half-functioning stage editor can be accessed by putting the following cheat in MAME's arkanoid.xml cheat file:  temp0 =maincpu.mw@0338 maincpu.mw@0338=8082 maincpu.mw@0338=temp0 This will bring up the level editor after starting a new game. Notes:
 * With this method, the controller can't actually be used to select blocks. Only the next block in the level can be selected.
 * After turning the cheat off, the game will freeze after Vaus respawns.

Staff Credits
84WZ3dzkrOY A set of staff credits (with pictures!) is still in the game, but it's normally inaccessible. There's no place to access it in the World board set, but it is accessible in the Japan set.

Put the following cheat in MAME's arkanoidj.xml cheat file. This will replace the Export warning with the credits.  maincpu.pb@c675=40

Unused Round
There's one unused round in the game. It's coded as Round 32, which is used for the Doh fight in the final game. This might have been used as a backup, just in case Doh failed to spawn for some reason. The easiest way to access this round is to go to Round 192.

Here's the arkanoid.xml code. Just beat Round 01 to get there:  maincpu.pb@ED72=9F

Build Date
A build string was displayed on the title screen when the game was still in development. The parameters for this string are defined in the main CPU at, but there's no call to actually display the text. Oh, and it's the same date in every version of the game.

This code (put in arkanoid.xml, in case that hasn't been made clear yet) will replace the "All Rights Reserved" string with the build date text.  temp0 =maincpu.mw@3336 temp1 =maincpu.mw@3339 maincpu.mw@3336=5CA9 maincpu.mw@3339=E698 maincpu.mw@3336=temp0 maincpu.mw@3339=temp1

Text Testing
Just some placeholder text for the game's scrolling text. Here's the cheat for the arkanoid.xml cheat file blah blah.  temp0 =maincpu.mw@770F temp1 =maincpu.mw@7711 maincpu.mw@770F=CD40 maincpu.mw@7711=BD37 maincpu.mw@770F=temp0 maincpu.mw@7711=temp1
