data file formatContext: See this workspace in context in the source code References: This workspace is used as follows: * SwapCode calls trackData
See the track source in revs-silverstone.asm for details of the track data. It covers trackData and dashData41 - the latter gets moved into screen memory as part of the memory-moving process in the SwapData routine.
