History

Released
January 1991
Music
Chris (Chris Ammermuller) -- "Outrun II Remix v2"
Group
X-Ray & Transcom -- Germany, founded 1988

A cooperative intro between two German groups -- X-Ray and Transcom -- released in January 1991. The soundtrack is Chris Ammermuller's "Outrun II Remix v2," a SID reworking of the iconic Sega arcade racer's music, preserved in the HVSC. No coder or graphics credits are recorded on CSDb. X-Ray was founded in Germany in 1988, while Transcom was a well-known German group that frequently partnered with other crews. The cooperation format -- two groups sharing a single intro -- was a common practice in the European cracking scene, signaling alliance and mutual respect. Chris Ammermuller's choice to remix Out Run reflects the era's fondness for game music adaptations on the SID chip. The group abbreviation "X+T" or "X-Ray+Transcom" appeared on numerous joint releases from this period. X-Ray's CSDb profile lists no members, making this music credit one of the few documented connections between Chris and the group's release catalogue.
