hi MamaLuigi HxD is safe to use. you can edit mission/sides/lvl files with it on the server files or client swbf1 swbf2 ps2 iso.

hi MamaLuigi i added your request to the original post 

to be able to use freecam on the swbf2 ps2 we need to hex edit the
COMMON.LVL using program HxD
from the game dvd placed into your dvd drive navagate to 2_01/DATA/_LVL_PS2  folder and copy COMMON.LVL onto your desktop for editing. load up your common.lvl just copied onto your desktop into HxD for edit. under the search header click it and find goto and click it.
in the box type 00013720
we are looking for freecam to change to console

66 72 65 65 63 61 6D = freecam
change to
63 6F 6E 73 6F 6C 65 = console

after making the change click file save your work. now your common file
is ready to be compiled into a new iso replacing the old one.

button usage in freecam
R1 up
L1 down
L3 forward backward left right
R3 *look* left right up down
DPAD  up: faster cam speed   down: slower cam speed

HxD can be found here https://mh-nexus.de/en/downloads.php?product=HxD
here is a link for the freecam common lvl  https://mega.nz/#F!fUATjZjA!BCjmGj_622Bb54J6ecCh9w
it needs rename after download to COMMON.LVL before placing it in the 2_01/DATA/_LVL_PS2  folder

i made a setup video for it when i was trying to help MamaLuigi get the server online hope this can help others . like Led said you will have to port forward 3658/3659 udp on your router/cable box/windows firewall/antivirus firewall

after more testing i was able to get the PAL swbf1 ps2 game online.
using these dns#'s
dns #1   45.7.228.197  xCrISTiAhNx
dns #2   67.249.159.113 bobz
also had to patch DNAS bypass the :SHELL:  UK_  ENG folders http://www.swbfgamers.com/index.php?topic=10250.0
also patched iso using IDCheck + Generator v1.0 - PE and windip 
 

thanks Mike for the eu dnas! thanks Led for adding it into your server machine! i will see if i can get it working in a few hours swbf1 ps2 eu.

tested it out using swbfspy dns# but keep getting error
-106 sceDNAS2_**_INVALID_SERVER
DNAS library (PS2) received an invalid server response. "DNAS Error (-106) A network authentication system error has occurred."

the eu game version works on the eu lan when testing.

the wireshark cap i got looks good but keep getting the error 106.

that is great that it works after putting the ps2 into the dmz.   
added files from the folder you sent and when trying to start server, it gives an error - "couldn't write server rotation file"
just to be clear the download folder from mega needs nothing added or removed. it is stand alone and can be extracted to desktop on winxp/win7/win10 and be used from any location on your pc or even separate hd/ssd. to test the server just double click the file SANDMAN'S REQUEST for testing. if the server box does not open then the common/Shell folder will need change.
what languge is your os in? if it is not english you will have to fix the common/Shell folder for the language your os is using.  the pic below shows all the supported languages the server is capable of supporting.

I know there's an option "create", but the created room doesn't seem to be visible in the lobby.
to make it show up in the lobby you will have to give your ps2 a static ip. port forward udp/tcp 3658,3659 on your router for the ps2 static ip. or put your ps2 in the dmz on your router with the static ip you gave it. it is best to use 2 ps2 one to play on and use the other to host the dedicated 16 man player. or you could run the server from a pc/old laptop. using the pc you will have to port forward the same above. if you want to test the server here are the files needed https://mega.nz/#!nRIDgTzD!7-a7a3qE-iovARdMG6PfltzpwedWZ7SCI8RZpRZxUko

hi Nster7 unfortunately there is not a dnas server that is hosted for the pal version at this time and this is why you get the error when trying to get online with the game dvd. you will need one of these memory cards with Free MCBoot on it to use the usa servers. http://www.ebay.com/itm/Free-MCBoot-1-953-FMCB-Playstation-2-64MB-Memory-Card-ESR-HDL-OPL-MORE-/272819038712?hash=item3f854829f8:g:gA8AAOSwSlBYtJAH

hi Nster7 how do you connect to the internet? cable modem/dslbox? are you using a router? is your game ntsc version? game version can be found on the spine of the game case. are you using the game dvd or the network startup disc to make the config *they are both the same and do the same job of saving the network config*? do you have a memory card for the ps2 to setup the network config and save it? if using a cable modem or dsl box plug the wire rj45 into the back of the ps2 and into the cable box/dsl box what ever you are using. then use auto setup selection from the startup disc/gamedvd. under dns# selection is option auto or manual on the startup disc/gamedvd use manual setup and enter in the dns numbers for ntsc = 74.91.125.138 and your second dns# 45.7.228.197                                     for pal version use dns #1   45.7.228.197  xCrISTiAhNx
dns #2   67.249.159.113 bobz test the connection from the startup disc/gamedvd if it is successful save the profile and name it swbfspy. after saving the profile on the memory card reboot the ps2. *if using the game dvd it will do this automatically* if using the cd network startup disc remove it. put the game disc in and try to play online select the profile you saved on the memory card. here is a vid showing how it is done to play in the servers.

hi Nster7 a few questions for you are you using a router is your game ntsc? or auto setup using the game disc or network startup disc? if using a router you will have to enter in the info for your router. in the vid example i enter in the info for my router. your router info can be found on a pc pluged into your router. click start then type run in search box.open run type cmd inside run box. a new box will open in the box type ipconfig/all copy down this info and use it to fill in the blanks on the network startup disc. also if using a router you will need to give your ps2 a static ip and port forward 3658,3659 to the new static ip for your ps2 or put your ps2 into the dmz. https://portforward.com/ is a great place for this info/setup help. the auto setup can be used with cable modem then changing the dns#'s to manual.  1# dns number = 74.91.125.138 and your second dns# 45.7.228.197
to use the pal servers use
dns #1   45.7.228.197  xCrISTiAhNx
dns #2   67.249.159.113 bobz

please note ps2 online currently it only works in usa. there are no dnas servers for eu or japan right now. PyroJockey was hosting a region free server ps2 swbf2 a few months ago not sure if it is still working anymore. but the problem is the setup of the dns# with the network startup disc. without the dnas server up for your region it makes it impossible to play online.

i have a vid on youtube how to setup the dns # using the network startup disc that comes with purchase of network adapter *fat ps2* or bundled with the *slim* ps2
thats basically all that has to be done to get online for ps2 other than pluging in the lan cable to your router/cable modem/dsl box to the port on the back of the ps2. what ever the client has. please note currently it only works in usa. there are no dnas servers for eu or japan right now.

here are some screen shot for the ps2 swbf1 lobby tankless, jet war cc, gladiator i admin. swbfspy ps2 is Rage's server. foxhound is Led.
for ps2 swbf2 Draculas is Draculas server. swbfgamers is Led.

thanks Linux user Awesome for all the late night battles
