Sonic the Hedgehog Pocket Adventure
In August 1999, SNK announced that they were collaborating with Sega to develop a "Sonic the Hedgehog" game for their Neo Geo Pocket Color handheld system. The game was developed by SNK, with supervision from Yuji Naka and Sonic Team at Sega. This marked the first time Sega was directly involved in the development of a "Sonic" game for a non-Sega platform. The team planned for "Sonic Pocket Adventure" to be a return to the classic 2D gameplay style found in the "Sonic" games on the Sega Genesis. In particular, many game design and visual elements are borrowed from "Sonic 2". The game's background music tracks are also 8-bit renditions of music from "Sonic 3". "Sonic Pocket Adventure" was released first in North America on December 4, 1999. SNK released a system bundle with the game included for the holiday season. The game was released in Japan two weeks later, and in Europe in February 2000.
History of Sega
To compete with Nintendo, Sega was more open to new types of games than its rival, but still tightly controlled the approval process for third-party games and charged high prices for cartridge manufacturing. Technicians from American third-party video game publisher Electronic Arts (EA) reverse engineered the Genesis in 1989, following nearly one year of negotiations with Sega in which EA requested a more liberal licensing agreement than was standard in the industry before releasing its games for the system. As a result, EA signed what founder Trip Hawkins described as "a very unusual and much more enlightened license agreement" with Sega in June 1990: "Among other things, we had the right to make as many titles as we wanted. We could approve our own titles ... the royalty rates were a lot more reasonable. We also had more direct control over manufacturing." The first Genesis version of EA's "John Madden Football" arrived before the end of 1990, and became what EA creative officer Bing Gordon called a "killer app" for the system.
