Network module replacement (ps2)

inada-s commented 4 years ago

The embedded protocol stack AVE_TCP is installed as irx modules in the PS2 game.
In the original implementation, the game communicate with game server through this module.
I think it is difficult to reuse this well, so it is better to develop the replacement module using ps2sdk's tcpip and use it instead of AVE_TCP.

I have no knowledge of the irx module, so I have to start with a survey. Fortunately, the irx module in the game still has debug symbols.

In the future, it may be better to provide patches for the original game iso image.

Do you think it is possible to create an IRX module that is able to use the broadband adapter instead of the modem? Another idea would be to reuse the modules from Monster Hunter or Gundam vs. Z-Gundam.

It is not possible to just replace the irx module. We need to patch the r5900 to skip the ppp step.

Skip modem operations (modem recognition, ppp connection).

This can be achieved by skipping some function calls on r5900. sample

Replace socket operations (TCP open, read, write, select, close, sockopt).

If we have a socket implementation, just plug it into it. sample
tcp/ip impl that use network adapter there is in ps2sdk.

Another idea would be to reuse the modules from Monster Hunter or Gundam vs. Z-Gundam.

Yes, I think this is another approach. Gundam DX already have AVE protocol stack and network adapter drivers, so we may just need to imitate how to use them.

The ps2 version of the game is easy to get, but unsatisfactory for fans. Perhaps it would be better to make the DC version playable on a emulator. So it's better to think about which version to use for playing before replacing the network module.

From my investigation, as long as we can emulate the correct server response, it is better to use https://github.com/flyinghead/flycast with the DC version.

Attached is the MODEM log (I've added the modem reg write log myself)

When the modem is going into the ringing state, it reads + dial the number from the 010 register.

So the DC version is using the MODEM to dial to 186-0053-63-13-1203, which matches the KDDI ISDN回線, also according to the KDDI call menu0053-63 is out of service.

From the PS2 MIPS code, I also found the game is dialing to a very similar number: 186-0053-63-13-1202

Finally the below is the full modem log, you can find that the game instructed the modem to dial a number, handshake correctly and the connection is established successfully. (all by modem emulation, no connection is made actually) Then the game is waiting for the initial data from the server, timed out, and close the connection (reset the modem)

thanks for good investigation! In the ps2 version, there was a big problem with connection in the battle scene, so I was thinking about what to do. I will also investigate the dc version.

inada-s commented 4 years ago

The ppp code seems to be disabled in the MSVC environment on Windows. In what environment did you debug?

inada-s commented 2 years ago

I decided not to fix this issue.

Network module replacement (ps2) #2

Skip modem operations (modem recognition, ppp connection).

Replace socket operations (TCP open, read, write, select, close, sockopt).
