Nintendo Entertainment System Hardware Clone - Software Game Titles

Software Game Titles

Since none of these unlicensed clones contain the 10NES authentication chip, most are capable of running games which an official NES model would not run. In addition, many modern NES clones come with a built-in selection of games, typically stored on an internal ROM which can range from 128 KB up to several megabytes in size.

These built-in games are usually designed to supplement, rather than replace, the traditional cartridge slot, although some devices omit such a slot entirely, allowing only the built-in games to be played. Typical numbers for the built-in "distinct" games range from as low as three to as high as fifty or one hundred games for more expensive products. The number of "distinct games" is important, because while many NES clones claim to have thousands of built-in games, most of these games are usually nothing more than hacks that allow the player to start the same game at different levels or with different numbers of lives.

The games are usually direct pirated copies of licensed NES and Famicom game titles, usually with copyright information removed and sometimes featuring other minor changes. The most commonly found games in NES clones are generally games below 64 K of ROM size and which can be easily split into distinct subgames or levels. As such, "Track & Field" and "Circus Charlie" are present in a large percentage of NES clones, usually blown up to count as 6 or 7 "distinct" games each. Duck Hunt (often with its clay shooting mode shown as a separate game) is also a common NES clone feature as they justify the existence of the light gun accessory. Other popular, although less common choices, are Super Mario Bros. hacks, Excitebike, Tetris, Magic Jewelry (an unlicensed clone of Columns) older sports titles and miscellaneous platform games. Additionally, some clones incorporate games which, although they may initially appear to be original, are in fact pirated copies featuring extensive graphical (and sometimes audio) modifications. Examples of this include UFO Race, based on Nintendo's F-1 Race, Pandamar (also known as simply Panda), based on Super Mario Bros., Ladangel, based on Hudson Soft's Challenger and UFO Shoot, based on Duck Hunt.

However, some systems include legally licensed games; for example, the Rumble Station's 15 built-in games are licensed from Color Dreams, and Sachen's Q-Boy includes only its own original titles. A growing number of recent clones, such as those marketed by DreamGear in the United States, contain large numbers of original games made by developers in China.
