Save file

There is one unfinished Okteta structure with some recognized values

Save file stores top scores, unlocked tracks/cars etc., sound volume (is setup.bin exists volumes from game.cfg is not used), current language, camera settings, but it doesn't seem to store graphics quality

setup.bin is by default saved to save/card00, however when the game starts it checks for first cardXX folder with that file. IT may happen that there is no setup.bin file in card00 and one exists in card01. In this case game will use that file.

Time - time/60 = seconds.milliseconds; 2181/60 = 36.35

Names written in bold are described in detail below the main table

Offset	Size	Description
0x0	0x4	File size, 0x211C
0x4	0x4	Checksum
0x8	0x16	Cars, first one is unused to have same indexes in table and car ID
0x1E	0x2	Zeroes, Last one could be used for next segments (track are 1-based, but arrays are 0-based, so this would be always zero)
0x20	0x19	Tracks, first one is unused to have same indexes in table and track ID
0x39	0x3	Zeroes
0x3C	0x16	Cars???, seems unused, first one is unused to have same indexes in table and ??? ID

0x8C	0x4	y image offset, can be set to <-31, 31> in hidden menu but can be set to arbitrary value, unsigned
0x90	0x4	Language id, in Polish version it's set to 1

0xFA	0x18	Connections between tracks in Arcade mode, each is stored as byte (0/1), read from left to right, top to bottom on the map

0xF1C	0xB00	Championship, array with 8 elements
0x1A1C	0x320	looks like array of sorts, 25 elements of 0x20 bytes each, similar to Arcade
0x1D3C	0x20	???, probably should be empty
0x1D5C	0x50	Championship money records, array with 10 elements
0x1DAC	0x50	Championship score records, array with 10 elements
0x1DFC	0x320	Stunts mode records, sorted array with 100 elements

Checksum

Read whole file, set bytes 0x4-0x7 to 0 (whole checksum), then loop over all bytes hash = int(data[i]) + ( hash >> 0x1D | ((hash << 3) % 2^32))

Arcade mode (each element is 0x20 bytes long):

Offset	Size	Description
0x0	0x4	lap time, def 20 1C 00 00
0x4	0x4	Player name, 3chars + \0, set to ...\x00 for empty scores
0x8	0x4	total time, def A08C0000
0xC	0x4	Player name, 3chars + \0, set to ...\x00 for empty scores
0x10	0x4	???, def 0
0x14	0x4	Player name, 3chars + \0, set to ...\x00 for empty scores
0x18	0x4	Stunts score, def 0
0x1C	0x4	Player name, 3chars + \0, set to ...\x00 for empty scores

After first record there is empty one and after that second record. All of them are very close to records array, how it it inserted then?

Championship (each slot is 0x160 bytes long):

Offset	Size	Description

0x100	0x60	Individual cars, array with 6 elements, 1st element is always player, unknown order of rest

Car parts

Each is 0x10 bytes long, first and last part ids determine available parts: <first id, last id>

Offset	Size	Description
0x0	0x4	If the part was changed, set to 1 after each race, set to 0 when part was changed or with clean championship save
0x4	0x4	Current part id, 0 for unused
0x8	0x4	id of first part, 0 for unused
0xc	0x4	id of last part, 0 for unused

Order of parts in array:

No.	Name
0	Unused
1	Unused
2	Unused
3	Shocks
4	Battery
5	Engine
6	Chassis
7	BMS
8	Brakes

Individual cars

Each element is 0x10 bytes long

0x8	0x4	Sponsor
0xC	0x4	??? Might be starting position

0x1A1C stuff:

Element at last index is not used, races 1-20 are sorted from 20 to 1, so after 1st race there is one entry near end of the table (minus one unused entry)

Offset	Size	Description
