Document 13: Nintendo Entertainment System: In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.
Document 14: Balloon Kid: "Balloon Kid" was designed by Yoshio Sakamoto. and developed by Nintendo in co-operation with the external company Pax Softnica. It was first published in North America in February, and finally in Europe on September 28.

According to Hitoshi Yamagami, director of "Balloon Fight GB", the Game Boy Color version was developed due to demand for a "Balloon Fight" sequel and that the success of "Game Boy Gallery" ""made them consider making an updated version of "Balloon Kid" for the Japanese market."" Both "Balloon Kid" and "Balloon Fight GB" were later re-released in their original regions as part of the Nintendo 3DS Virtual Console lineup; however, the "VS Mode" became incompatible.
Document 15: Nintendo Entertainment System: As the 1990s dawned, gamers predicted that competition from technologically superior systems such as the 16-bit Sega Mega Drive/Genesis would mean the immediate end of the NES’s dominance. Instead, during the first year of Nintendo's successor console the Super Famicom (named Super Nintendo Entertainment System outside Japan), the Famicom remained the second highest-selling video game console in Japan, outselling the newer and more powerful NEC PC Engine and Sega Mega Drive by a wide margin. The console remained popular in Japan and North America until late 1993, when the demand for new NES software abruptly plummeted. The final Famicom game released in Japan is Takahashi Meijin no Bōken Jima IV (Adventure Island IV), while in North America, Wario's Woods is the final licensed game. In the wake of ever decreasing sales and the lack of new software titles, Nintendo of America officially discontinued the NES by 1995. However, Nintendo kept producing new Famicom units in Japan until September 25, 2003, and continued to repair Famicom consoles until October 31, 2007, attributing the discontinuation of support to insufficient supplies of parts.
