How to edit IP.BIN TOC for CDDA track?

[SunDragon]

Has noticed, that in many releases it is changed TOC (Table of contents) in IP.BIN.
What for and how these values change?

For example in game Trick Style:

IP.BIN - original GD-ROM

...(hex)
00000100:  54 4F 43 31-5E B0 00 41-A8 50 05 01-F7 81 05 01
00000110:  77 B6 05 01-45 04 06 01-FF 3C 06 01-EE 76 06 01
00000120:  22 A3 06 01-A4 DC 06 01-3D 0A 07 01-85 46 07 01
00000130:  11 8B 07 01-69 C1 07 41-FF FF FF FF-FF FF FF FF
...
00000280:  FF FF FF FF-FF FF FF FF-00 00 03 41-00 00 0F 41
00000290:  B4 61 08 41-00 00 00 00-00 00 00 00-00 00 00 00

IP.BIN - the same IP.BIN but is changed

...(hex)
00000100:  54 4F 43 31-36 A2 00 01-8E A4 00 01-DD D5 00 01
00000110:  5D 0A 01 01-2B 58 01 01-E5 90 01 01-D4 CA 01 01
00000120:  08 F7 01 01-8A 30 02 01-23 5E 02 01-6B 9A 02 01
00000130:  F7 DE 02 01-FF FF FF FF-FF FF FF FF-FF FF FF FF
...
00000280:  FF FF FF FF-FF FF FF FF-00 00 03 41-00 00 0F 41
00000290:  4F 15 03 01-00 00 00 00-00 00 00 00-00 00 00 00
