The relative ease of copying games software in the 1980s, at the time predominantly distributed on audio cassettes or diskettes, caused games producers to lose substantial revenue due to software piracy. The emergence of games consoles using cartridges as the software distribution media promised to radically reduce casual piracy, as the equipment to reproduce cartridges or overcome their security was not generally available to the average consumer in the same way as an audio cassette recorder or disk drive was. At a gaming convention in 1985, the Stamper brothers proposed their work to Nintendo of America. At the time, Nintendo had been enjoying high sales from their third-generation Nintendo Entertainment System and in-house titles, and were not interested in licensing their work. Undeterred, Tim Stamper spent six months cracking the Nintendo code. At the next gaming convention, the Stampers arrived with a skiing game called Slalom, making for a better reception. Nintendo bought the game for an undisclosed amount, adding that to their in-house "Sports Series" and granted a license to Rare to create games such asBattletoads, Donkey Kong Country, Killer Instinct and GoldenEye 007 for Nintendo systems. Most recently Rare created Kameo: Elements of Power, Perfect Dark Zero and Viva Piñata for Microsoft's Xbox 360.
On 2 January 2007, it was announced by 1UP.com that both Tim and Chris Stamper had left Rare to "pursue other opportunities", leaving no statement regarding plans.
In 2004 Tim Stamper paid £17m for Eydon Hall in Northamptonshire.
