and miscellaneous platform games. Additionally, some clones incorporate games which, although they may initially appear to be original, are in fact counterfeit 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 Technologies in the United States, contain large numbers of original games made by developers in China. Hardware and software compatibility While most Famiclones will run most original licensed Nintendo software and work with most original carts (being even more versatile than an original NES because of the lack of regional lockout chips and sometimes having a dual 60-pin and 72-pin cartridge compatibility), the degree of hardware compatibility with original NES accessories and miscellaneous hardware equipment may vary, and even software level compatibility is not always perfect. The most common software-level incompatibility in the built-in games that some sport, is the lack of save RAM, causing the few games that use it to fail when trying to save or load data. Since most modern Famiclones are based on the NES-on-a-chip ASIC, they automatically inherit all of its limitations, which includes graphical glitches and compatibility issues. At a hardware level, the most common incompatibility is the lack, in some Famiclones, of the original Famicom's expansion port (although it is always present, at least at a logical level, and in some clones it is internally hardwired; e.g. in computer-type Famiclones it is hardwired to the built-in keyboard, even if not externally accessible). Some Famiclones also use standard Atari 9-pin shaped or even 15-pin joypad connectors instead of the proprietary NES connectors, and their controllers usually offer all of the functionality of a standard NES controller and sometimes features such as "slow motion" or several autofire keys with different speeds, which are not present on the standard out-of-the-box NES joypads. Despite being physically identical to Atari 9-pin, the protocol is different: Atari uses a parallel protocol where each wire carries the status of a single button, and Famiclones uses the same 4021-based serial protocol the original NES used.
