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

0x39	0x3	Zeroes
0x3C	0x16	Cars???, seems unused, first one is unused to have same indexes in table and ??? ID

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?
