fooling with m2emu network

(1/64) > >>

SailorSat:
Long Story short...

The network code in m2emulator 1.1a is a mess.

Grab a copy of the patched m2emulator 1.1c from http://files.arianchen.de/m2em/emulator_multicpu_11c.zip
( might want to rename it instead of replacing the existing one )

Turn on FrameSync in m2network.ini

If using ONE machine set your RXPort and NextPort
If using MULTIPLE machines only set NextIP the next machine

Known issues:

Random Freezes
You might experience random "freezes" for about 2 seconds.
This happens when packets are lost somewhere.

Flickering cars (in any game)
No reliable fix known - Works fine if the network is forcefully slowed down, which causes audio stuttering.
Need to "fix" the timers in m2em at some point.
Likewise turning on V-SYNC and running the game at 58Hz helps something, while breaking audio.


Changelog - sort of


* 1.1b - added a timeout for receiving packets, so the MASTER mode on the newer (2B / 2C) games won't finish initialisation before it has been setup.
* 1.1c - changed receiving handle incoming packets before sending out any data.

Nuexzz:

thank you very much SailorSat  :notworthy: :notworthy:

We can do some online testing tool in beta version?
