MANDATORY core file change effective for the Lowes Revamped 2008 race next Dec 12, 2009 Monday night. The results are in from the pole and the information about updating core ini file is posted in the forums.

Everybody needs to make changes to the core.ini file on their PC which is usually located at C:PapyrusNascar Racing 2003 Seasoncore.ini

I have a supplied ini files in the downloads section of the website or click on link http://www.noraracing.com/downloads/NORACoreFiles.zip there is an original one and an updated one.

I also have some exe programs http://www.noraracing.com/corefileprograms/ if you want to rely on some software programs.

Personally I prefer to update settings mannually as I have adjusted that core file for lengthy replays some others for graphics. But please read below for more information on how to and what and were to alter. Some FAQ's there for you too.

There is only four lines in which to change the number from a 2 (first two lines below)or 3 (last two lines below) to a 1 in the communication block.

net_lan_client_send_every=1

net_lan_server_send_every=1

net_mdm_client_send_every=1

net_mdm_server_send_every=1

Because I run multiple computers with NR2003 through my modem, I also had to switch the line below - but most racers will not have to change this line.

net_use_mdm_bandwidth_for_tcp_ip=0

Manual editing:

- Navigate to your NR2003 directory and open the core.ini file (it should open with Notepad).
- Change the values of the highlighted lines so that your file matches those listed below, you'll find them listed under [Communications] near the top of the file:

Quote:

[Communications]
alternate_ip_addr_lookup=1 ; Find IP addresses another way
bcast_listserv= ; IP address of race list server
bcast_listserv_port=0 ; list server port (0 = default)
bcast_listserv_req_freq=0.000000 ; Request race list frequency
bcast_ping_disable=0 ; Disable response to pings
bcast_send_disable=0 ; Disable sending broadcasts
bcast_send_freq=4.000000 ; Broadcast frequency (seconds)
disable_direct_connect=1 ; Disable Direct Connect
disable_icmp_checking=1 ; Don't open/check ICMP sockets
disable_ipx=0 ; Disable IPX support
disable_modem=0 ; Don't look for/use modems

log_server_comm_errors=0 ; Log errors for client channels?
log_server_connect_status=0 ; Issue messages as clients connect
mem_client_send_every=1 ; Client packet freq via memory
mem_client_send_size=532 ; Client packet size via memory
mem_server_send_every=1 ; Server packet freq via memory
mem_server_send_size=1028 ; Server packet size via memory
net_lan_client_send_every=1 ; Client packet freq on LAN
net_lan_client_send_size=260 ; Client packet size on LAN
net_lan_server_send_every=1 ; Server packet freq on LAN
net_lan_server_send_size=772 ; Server packet size on LAN
net_mdm_client_send_every=1 ; Client packet freq on dialup
net_mdm_client_send_size=116 ; Client packet size on dialup
net_mdm_server_send_every=1 ; Server packet freq on dialup
net_mdm_server_send_size=116 ; Server packet size on dialup
net_server_port=0 ; Server port number (0 = default)
net_use_mdm_bandwidth_for_tcp_ip=0 ; Use modem bandwidthfor TCP/IP

It is vital that your core.ini file matches the values above, it is essential the lines in red are correct.
Save and close the core.ini file then open it again and confirm the values are correct.

That's it, you're done and can enter the server, if you race anywhere else then the values will need changing back before entering other servers, the values to change back is everything you just changed to a 1, change it back to a 2.

--------------------------------------------

FAQ:
Why change netcode settings?
Remember racing offline, hitting an AI and they're solid as a brick? That's what it will be like racing online with these new settings if you hit another car - it still doesn't stop some things "operator behind the wheel" related but it does improve door to door and bumper to bumper contact - the car position is updated to all players at twice the datarate of normal and so it's easier to go side by side in a corner with someone without warping into them. The new code allows for closer racing, it doesn't give you a license to go banging and beating on the guy or girl in front, the same physics still apply so most contact will still result in at least 1 car crashing.

Is it mandatory?
Yes, not making the change places additional strain on the server which can compromise everybody elses connections.

Why fix what isn't broke?
To be frank, the netcode is broke, this game was designed to run on 56k modems NOT broadband connections, there a way too many cautions caused by bumps that would with this code result in no accident, there is a known fix, so why shouldn't we at least try it?

What about racing on other servers?
You will likely need to change the values back.

I made the changes, entered the server, clicked drive and was disconnected - why?
You or the updater hasn't applied the changes correctly, please check the path is correct for the updater or double check your core.ini file and make sure the last line has a value of 0 if it has a value of 1, then this is what causes you to be disconnected, regardless of whether the other values are correct, if the last line is incorrect you game is limited to a 56k speed connection to the server and this is why you got disconnected.

If you experience this, DO NOT continue to connect, click drive, disco, connect, click drive etc. etc. this puts massive strain on the server and compromises everybody elses' connection, if you are disconnected once after clicking drive, rejoin the server and contact the in-race admin for assistance.

If you have any questions regarding this or making the changes, please make a post or contact a member.
