Not all ports of the game are perfect reproductions across the board.

The first port of the game was released on the Dreamcast.

Some ports of the game include a split-screen two player mode.

However, this port of the game was never released.

A port of the game to the iPad is already out.

Some of these features were implemented in the ports of the game.

Later, ports of the game were released without the erotic content.

It was far better received than the port of the original game.

It also contained remixed music, like the port of the first game.

This is the only port of the game to feature such pictures.
