Chiki Chiki Boys (チキチキボーイズ), also known as Mega Twins in the original arcade release in the west, is an arcade game by Capcom first released in 1990 and ported to the Sega Mega Drive in 1992 by Sega and Visco. The game features two twins who are attempting to re-take control of their land, Alurea, after a monster unexpectedly attacks, destroying everything in its path.


The people of Alurea have lived in peace for a thousand years and have forgotten how to fight, yet the land's only survivors, the twin sons of the king, must take up the challenge and return their kingdom to its former glory.

The two twins, aged around 15 at the time the game takes place, venture forth in search of a legendary stone known as "Dragon Blue Eyes," which is rumoured to be able to put everything back to rights.


The game takes the form of a scrolling platform/beat 'em up game, with the players controlling the characters of the twins. The game can be played alone (in which case only one of the twins is present), or with two players together controlling one twin each.

In addition to moving around, the players can jump (C) and also cling on to vertical walls, allowing them to climb to areas that would otherwise be out of reach. Each player is armed with a magic sword (B), which is the main weapon used against the enemies in the game. Magic bombs can also be collected as the game progresses, each of which will cause damage to all enemies on the screen when fired (B). Only a limited number of these bombs can be carried by the players at a time.

Each player has an energy bar which is depleted each time contact is made with an enemy or projectile. When the energy reaches zero, the player loses a life.

Chests are scattered throughout the game (some of which are hidden and must be discovered), the majority of which contain coins that add point to the players' scores, but some of them contain power ups and bonuses such as a pill that replenishes the players' energy bars and an enhanced magic sword.


The game is made up from nine levels, which are as follows:

Round 1 - The Earth
Consists of a forest section and a lava-filled cavern. The goddess Callia is encountered at the end of this level.
Round 2 - The Heavens
At the end, the Shrine of Meius, the god of the heavens, is reached.
Round 3 - Under the sea
The twins travel through a haunted sunken pirate ship.
Round 4 stage 1
Jungle/crystal caverns.
Round 4 stage 2
The underwater foundations.
Round 4 stage 3
The monster castle dungeon.
Round 4 stage 4
Into the sky.
Round 4 stage 5
Ascent to the top of monster castle.
Round 5
Escape to paradise.

The player is able to select to start on any of the first three levels, but the remaining levels can only be accessed sequentially.


The most conspicuous change in the Mega Drive version of Chiki Chiki Boys is the lack of the two-player mode found in the arcade version. Otherwise, it is relatively faithful, save for minor cutbacks in graphical quality (both in the form of fewer colours, less detailed backgrounds and foregrounds, and some minor visual effects). While the stages have the same layouts, in the Mega Drive version they are not continuous like the arcade; instead they are divided into sections which are separated by black screens, presumably as the console loads a new set of graphics. Also, the Mega Drive version also lacks the time limit seen in the arcade.

In the arcades, Chiki Chiki Boys runs on Capcom's CPS hardware with an internal resolution of 384x224, which is then squashed to fit a 4:3 monitor. As such, all of the graphics were purposely drawn wide by the original artists in the knowledge that the image would "correct" itself before being shown on screen. The Mega Drive version appears to borrow graphics from the arcade, however as the console renders the game at 320x224, this correction process does not occur and the majority of the visuals are therefore too wide.
