RUN "+" to run the game.
Analog joystick required in right port. Left/right steers, up/down is acceleration/braking.

RENAME.BAS utility lets one rename and/or delete tracks. Up to 10 characters per track, but first 8 (the filename) must be unique.

Tracks on REVOLUTION disk:
(NOTE: I fixed half a dozen that were not showing up, and got rid of 5 that didn't exist. LCB)
(NOTE 2: According to reviews from the time, there were 10 tracks included when one purchased the game.I don't know which of the ones on the archive copy (including the ones I recovered) are originals and which were created by the person whose disk this is an image of.

Programming notes:
==================
The menu is controlled by RECORDS.DAT which has the track name and the record for the track (time and winners name) and track widths (I think just for sorting... the tracks have a width embedded in them already).

NOTE: The game saves the last track/car you ran it with.
Game does a PCLEAR 6 and CLEAR 2200,&H6300. There are 7 DEFUSR routines, which appear
to be a jump table:
0=$6300
1=$6303
2=$6306
3=$6309
4=$630C
5=$630F
6=$6312
So ML code is $6000-$6FFC
Track data is $7000-$7xxx
end address should $7000+(file size-$22 (34))


LINE 7000 - change track
LINE 7200 - Get track selection
LINE 8000 - Load track from disk
  FI$ - 10 char track name (left 8 is the track name for TRKNAME.TRK file)
  FE$ - 8.3 track name - this is LOADM'd.
LINE 9000 reads in RECORDS.DAT into TF$(xx) (1 for each track)
LINE 9500 Saves records
LINE 9600 builds the record(s)
LINE 9900 Sorts the list alphabetically (the whole field)
LINE 9800 Decode records

=====================
Data in RECORDS.DAT
When the program creates them, it makes 34 spaces then a "/" to pre-initialize an entry (line 9626) into TF$ (not the array, the regular variable)

TF$(xx) - track record data from RECORDS.DAT (see structure below)
LR = time record for current track VAL((MID$(TF$(xx),13,6)). NOTE: 999 is a special flag for a newly made track that has no record yet. I will use 998 for the tracks that are missing from RECORDS.DAT.
LH$ = MID$(TF$(xx),20,10) (Name of current best time holder)
CR = VAL((MID$(TF$(xx),31,1)) (car # 0 to 3: VW, PORSCHE, LOTUS, FERRARI)
TW = VAL((MID$(TF$(xx),32,3)) (includes '/' as 3rd char)
L = # of laps player requested.
TW=Track width (based on difficulty level selected when creating a track)
E=end address of track data (starts with 3 byte header @ $6FFD, track data at $7000).
  This is based on the "track end" address stored at $6FFE-$6FFF, +20.
TL = Track length (end address-$7000)/4. So each vertical block uses 4 bytes

Each record is 36 bytes ($24)
Structure:
$00-01 (2 bytes) - ASCII track width (STR$(11-TW)). So this goes from 1 to 5, and other width at $20-$21 goes in the opposite direction with no offset:
1 - 10
2 - 9
3 - 8
4 - 7
5 - 6
6 - 5
7 - 4
$02-$0B (10 bytes) - name of track (10 chars max, space padded)
$0C-$11 (6 bytes) - best time on track (right justified) sss.dd (s=seconds, d=decimal seconds)
$12 (1 byte) - always a space so far
$13-$1D (10 bytes) - left justified name of track record holder
$1E - a single digit Car type # 0-3 (VW to Ferrari) player used for record time
$1F - always a space so far (sign of ASCII track width)
$20-$21 - 2 digits, space padded, left justified (track width with no adjustments)
$22 - always a slash so far
$23 - CR

======================
Data in *.TRK files (after LOADMing it)
These all load starting at $6FFD
$6FFD = track width
$6FFE-$6FFF = end address (based on length of track*4 + 20+. TL gets (E-&H7000)/4. The SAVEM for a track is $6FFD,E,$A027 (the latter is reset vector
$7000-xxxx =
