For those who want to get into the zone 21. (Freelancer)

I don't have long climb and learned that the jump gates (gates from system to system) in the file li01 differ specifically in the ini file so I have not tried it myself but you try
1. Go to the main directory of the game freelancer and the search engine to drive this is li01 after searching to watch a file path, it should be like this Freelancer\DATA\UNIVERSE\SYSTEMS\LI01\li01.ini
2. Open this file in any suitable application (even Notepad) to find the score of the word (in the search of Notepad) nickname = Li01_to_Li05
3. Look above and you will see a jump gate in li04 (CA) here is a quote:
[Object]
nickname = Li01_to_Li04
ids_name = 260913
pos = 68666, 0, 60396
rotate = 0, 20, 0
Archetype = jumpgate
msg_id_prefix = gcs_refer_system_Li04
ids_info = 66145
jump_effect = jump_effect_bretonia
reputation = li_p_grp
behavior = NOTHING
difficulty_level = 4
goto = Li04, Li04_to_Li01, gate_tunnel_bretonia
loadout = jumpgate_li_01
pilot = pilot_solar_hardest

then compare it to the jump gate in li05 (Alaska)

[Object]
nickname = Li01_to_Li05
ids_name = 260914
pos = 80632, 0, 12299
rotate = 0, 105, 0
Archetype = jumpgate
msg_id_prefix = gcs_refer_system_Li05
ids_info = 66145
jump_effect = jump_effect_bretonia
reputation = li_n_grp
visit = 0
behavior = NOTHING
difficulty_level = 10
goto = Li05, Li05_to_Li01, gate_tunnel_bretonia
loadout = jumpgate_li_03
pilot = pilot_solar_easy
4 You will see the difference in these lines
reputation = li_p_grp (in Jump gate California)
reputation = li_n_grp (in jump gate Alaska)
reputation = li_p_grp (jump gate in the system ли03 I don't know what this kind of system but it is higher than California)
The difference between them in a single, specifically in the letter P and N, the letter N as if forbids passage to a particular system simply replace N by P and try. ALL enjoy the flight (has Not been Tested it's best to Save the Original Files In a Different Folder)
