意思是不能网络对战了？？
那个0.87-0.88.diff
是用来干什么的？？
是不是网络补丁啊，，怎么用？
我在邮件列表看老美说了一大阵子怎么支持网络。最后是一大块代码。。。
看得一头雾水。。。郁闷。
原文如下，供大虾参考：

[Xmame] mamenet lives! sorta
From: Steve Freeland
Subject: [Xmame] mamenet lives! sorta
Date: Fri, 07 Dec 2001 16:04:43 -0800
Here is a very preliminary patch against xmame 0.56.1 to enable
network multiplayer. Only the basics are implemented (see TODO in
doc/multiplayer-readme.txt) but it should be enough to play most games on a
LAN. I doubt you'd have much luck over the internet, and playing over
anything slower than a cable modem is definitely not going to be pleasant.
Still, it's a start. I would've given it some more work but I'm
sending it in now in case some of you want to play around with it over the
weekend -- I probably won't get back to it before Monday.
Enjoy, and good luck...

--- 1,90 ----
+ Multiplayer Network XMame N0.1 (Rewrite by Steve Freeland,
[EMAIL PROTECTED])
+ ------------------------------
+ mame version 0.56.1
+
+ Usage (for an n-player game):
+ -----
+ Start a master:
+ xmame.<display method> -master n <other options> <game name>
+ Start n - 1 slaves:
+ xmame.<display method> -slave <master hostname> <other options> <game name>
+ Currently there can only be one slave per machine, although a slave
+ can share a machine with the master.
+
+ Message format
+ --------------
+ Each UDP packet has a 4-byte header followed by a body.
+ The header has a 3-byte magic string "XNM" followed by a 1-byte message type.
+ The contents of the message body depends on the message type, and there may in fact
+ not be a body.
+
+ Message types: See enum net_msg_type in src/unix/network.c in case
+ ------------- this doc is out of date
+ JOIN: This is the first message the slaves send to the master for
+ handshaking. The body contains a string identifying the slave
+ (<hostname>/<pid>), the slave's MAME build version and net protocol
+ version, and the name of the game being played. If any of the latter
+ 3 do not match the master's information, the master will refuse the
+ join. The slave id string is currently only used for logging.
+
+ ACCEPT: This is the master's reply to the slave if the protocol
+ versions and game name match. The 1-byte body is the player number
+ assigned to the slave.
+
+ REFUSE: This is the master's reply to the slave if the protocol
+ versions and game name do not match. There is no body.
+
+ LOCAL_STATE: This message is sent by the slave to the master and
+ contains a sequence number (see Protocol below) and a byte
+ order-adjusted copy of the slave's current input_port_values[] array.
+ It is used by the master to compute the global state.
+
+ GLOBAL_STATE: Sent by the master to each of the slaves and contains,
+ like LOCAL_STATE, a sequence number and a byte order-adjusted copy of the
+ input_port_values[] array. The slave uses this to overwrite its own
+ local copy of input_port_values[].
+
+ QUIT: Sent when a client or the master exits and allows the remaining
+ participants to handle the exit gracefully without having wait for a timeout.
+
+ Protocol
+ --------
+ For frame n:
+ . Slaves all send input state for frame sequence number n to master.
+ . Master waits indefinitely for all slave inputs for frame n to
+ arrive.
+ . If the master receives a slave input for frame n - 1, that
+ slave may not have received the global state for frame n - 1
+ and the master must resend it.
+ . If the master receives a slave input for frame < n - 1, that
+ can only be due to out-of-order delivery (I think) and it
+ can be ignored.
+ . Master eventually receives all slave input state, merges them and
+ sends the global state back to slaves, then processes (eg,
+ proceeds with emulation until the next frame) the merged
+ input and goes back to waiting for local inputs for frame n + 1.
+ . Slaves wait a certain amount of time for the global input state
+ from the master.
+ . If the wait times out then the local input state for frame n
+ is resent.
+ . Slave may receive an old response (frame < n) due to out-of-
+ order delivery, which it ignores. If frame is n - 1 is
+ received that could be due to a premature resend.
+ . Slaves eventually all get the global state for frame n, then
+ process the merged input and proceed to the next frame.
+ . Lather, rinse, repeat.
+
+ TODO
+ ----
+ . Handle user interface invocation?
+ . More flexible port config?
+ . Adjust for high latency -- coarser sync frequency?
+ . Player n to player 1 input port remapping
+ . Talk to the core team about integrating the protocol-level stuff
+ into the platform-independant network.c
+
+ Old readme:
