Hi.
I have World War II Mod installed for Battlefield Vietnam and noticed that if running the game and then going to Options->Custom Game in the menu, the game asks to insert a CD. Same thing if running the mod with

+game BFV_WW2Mod

and then trying to join some server.

I tried old crack from Joker and there is no such problem with that.

So I did a diff on the exes, and found out, that team-simple crack has changed

E8 E7 FE FF FF

to

B8 01 00 00 00

near the beginning (line 3460 if using vbindiff) and reverting that change makes custom game also work.

It's also the same in original exe, so what was this change supposed to do in team-simple crack? Everything *seems* fine after reverting to original.

Hi

Battlefield Vietnam uses a different Gamespy protocol than Battlefield 1942. (enctype X if going by Luigi, or QR2/Encoding 3 if going by Gamespy now-open-sourced SDK).

I have implemented master server for servers list and it works in Battlefield Vietnam as long as I have not enabled including all basic keys. The thing is that I have correct implementation based on latest Gamespy client implementation as different demo apps work well with my server - with and without basic keys. So I'd be really interested if somebody has real tcp dumps (hopefully with also the secret sent by client) for port 28910 from the time gamespy was still serving.

Alternative would be debugging BFV on why it is not showing anything when loading the list with basic keys included, but I lack enough expertise in RE to do that.

// I have tried adding only one server, in which case packet size limit should not be a problem as well.
