The ninth crack intro from Red Sector Inc. — a Canadian cracking group founded in 1985 and active until the end of 1993. CSDb (group ID 602) classifies RSI as a demo group, cracker group, and fixing group, with a roster exceeding 80 members across its eight-year lifespan. The group was established by Billy Best, Greg, and Kangol Kid, and was rebuilt on the C64 in August 1992 by Irata, Mr. President, Psychobilly, Benson, and Termo. RSI earned a reputation as "the best 1st release group on the C64" during 1993 and produced approximately 280 releases over its full span. This intro features a modified version of O. Klaewer's "Zero Gravity" and was noted on intros.c64.org for containing anti-rip protection that caused crashes after extended runtime. RSI should not be confused with the better-known Tristar & Red Sector Inc. (TRSI), a separate German entity listed under CSDb group ID 915. Key members included coders Count Zero and Psychobilly, alongside crackers Irata, Mr Zero Page, and Dense.
