The Nürburgring consists of the following track sections: 0 || Romer Kurve to Castrol-S (1/2) 1 {} Romer Kurve to Castrol-S (2/2) 2 |->| Castrol-S (1/2) 3 <- Castrol-S (2/2) 4 {} Castrol-S to Ford Kurve (1/4) 5 {} Castrol-S to Ford Kurve (2/4) 6 <- Castrol-S to Ford Kurve (3/4) 7 || Castrol-S to Ford Kurve (4/4) 8 -> Ford Kurve 9 || Ford Kurve top Dunlop Kehre (1/2) 10 |<-| Ford Kurve top Dunlop Kehre (2/2) 11 -> Dunlop Kehre 12 {} Dunlop Kehre to Bit Kurve (1/7) 13 <- Dunlop Kehre to Bit Kurve (2/7) 14 || Dunlop Kehre to Bit Kurve (3/7) 15 -> Dunlop Kehre to Bit Kurve (4/7) 16 {} Dunlop Kehre to Bit Kurve (5/7) 17 <- Dunlop Kehre to Bit Kurve (6/7) 18 || Dunlop Kehre to Bit Kurve (7/7) 19 -> Bit Kurve 20 {} Bit Kurve to Veedol Schikane (1/3) 21 -> Bit Kurve to Veedol Schikane (2/3) 22 {} Bit Kurve to Veedol Schikane (3/3) 23 <- Veedol Schikane (1/2) 24 -> Veedol Schikane (2/2) 25 {} Veedol Schikane to Romer Kurve 26 -> Romer Kurve where each section is one of the following shapes: || is a straight section that doesn't curve to the left or right, and has the same gradient throughout the whole section {} is a straight section in the sense that it doesn't curve to the left or right, but the gradient can differ between sub-sections -> consists of sub-sections that all curve to the right <- consists of sub-sections that all curve to the left |->| consists of sub-sections that are either straight or curve to the right |<-| consists of sub-sections that are either straight or curve to the left |<->| consists of sub-sections that are either straight or curve to the left or right This part defines the following aspects of these track sections: trackSectionData Various data for the track section: * Bits 0-2: Size of the track section list Defines the number of entries that we store in the track section list for this section, which is used to calculate the coordinates of the track verges (higher numbers mean more sections are calculated, so higher numbers are used for more complex parts of the track) This value is given in the bottom nibble of the track section data byte (bit 3 is ignored), i.e. the second digit in the hexadecimal value * Bits 4-7: Sign number The number of the road sign (0 to 15) to show when we enter this section, but only if the sign number is different to the number in the previous section This value is given in the top nibble of the track section data byte, i.e. the first digit in the hexadecimal value xTrackSectionIHi High byte of the x-coordinate of the starting point of the inner verge of each track section yTrackSectionIHi High byte of the y-coordinate of the starting point of the inner verge of each track section zTrackSectionIHi High byte of the z-coordinate of the starting point of the inner verge of each track section xTrackSectionOHi High byte of the x-coordinate of the starting point of the outside verge of each track section trackSectionTurn The number of the segment towards the end of the section where non-player cars should start turning in preparation for the next section zTrackSectionOHi High byte of the z-coordinate of the starting point of the outside verge of each track section trackDriverSpeed The maximum speed for non-player drivers on the next section of the track Some of the trackDriverSpeed values have been scaled down by a factor of 1.44 from the Commodore 64 version. This applies to sections that are followed by sections with bit 7 of trackSectionFlag set. Those sections are 1, 5, 7, 10, 16, 18 and 22, and this scaling is noted in the comments below. See part 2 of the track section data for each section's trackSectionFlag, where Sp=1 denotes sections with bit 7 of trackSectionFlag set (so we scale trackDriverSpeed in the sections that precede these).
