1.
打开conf 文件夹里面的 bnetd.conf 按照下面的修改
# If you disable this you must have one or more of the MPQ files. Otherwise
# clients will hang when they first connect because they are attempting to
# download them. The versioncheck can only be skipped for clients older
# than 109. Starting with version 109 the clients will always do version
# checking since they do not function properly if the server does not
# request it.
skip_versioncheck = false
# If you enable the version checks but want to allow clients that don’t pass
# the checksum test then enable this.
allow_bad_version = false
# If you enable the version checks but want to allow clients that aren’t
# listed in the versioncheck configuration file then enable this. Unless
# you have a very complete file or are very paranoid about cheaters this
# is a good idea.
allow_unknown_version = false
改完这3个 登录时 就会验证 魔兽 的版本，
找到”loglevels =”这里，改成 loglevels = fatal,error,warn,info,debug,trace
# Multiple log levels can be defined by connecting them with a comma (,)
# Available loglevels are:
# none
# trace
# debug
# info
# warn
# error
# fatal
#loglevels = fatal,error,warn,info,debug,trace
loglevels = fatal,error,warn,info,debug,trace
改完这一个，就会纪录所有的信息，包括 错误，警告，信息，等
先删除以前的日志，即 var文件夹里面的bnetd.log
保存运行pvpgn.exe，然后用1.21版的魔兽登录 战网，会提示 不能验证游戏版本，然后退出魔兽
2.
打开 versioncheck.conf
看到 现在 支持 1.20e 的版本信息
# Warcraft III – TFT (Expansion) 1.20e
# Note: this version check is sent in both FT and ROC mode
“A=3845581634 B=880823580 C=1363937103 4 A=A-S B=B-C C=C-A A=A-B” \

0x8771b225 \
WAR3_120E
第一行，游戏类型，游戏版本
第二行，查找bnetd.log文件，搜索selected “IX86ver1.mpq”，这行后面会有一段类似”A=3845581634 B=880823580 C=1363937103 4 A=A-S B=B-C C=C-A A=A-B”
这样的代码
第三行，X86系统都用的是 IX86ver1.mpq，一般直接复制过来就可以。如果你用的是mac那就自己相应的改一下。
第四行，IX86是系统类型，一般也不用改，在bnetd.log里面搜索”archtag=”，等号后面的就是
第五行，游戏版本，SEXP就是星际争霸母巢之战，W3XP就是冰封王座，在bnetd.log里面搜索”clienttag=”，等号后面的就是
第六行，游戏exe版本，搜索log，在bnetd.log里面搜索”exeinfo=”。
第七行，版本ID，搜索log，在bnetd.log里面搜索”versionid=”
第八行，版本数字代码， 在bnetd.log里面搜索”verstr=” 冰封王座1.20e 就是 1.20.4.186 ，1.21a 就是 1.21.0.119
第九行，检验码，搜索log，在bnetd.log里面搜索”checksum=”
第10行，游戏类型_版本号，比如说冰封王座就是 W3XP,1.20e版就是1.20e，那就写 W3XP_120e
打开var文件夹里面的bnetd.log 来到文件尾部

按照这个上面的步骤修改完毕，删除老的版本信息，就是 让战网不支持1.20甚至更低的版本
但是 硬盘版魔兽 用 剑心的1.21a傻瓜补丁升级的，不能登录
经过一番研究，得以解决
因为 剑心 的 1.21a 傻瓜补丁 问题很大，所以 我又用 剑心的补丁升级，重复上面的步骤，
得到
# Warcraft III – TFT (Expansion) 1.21a
# Note: this version check is sent in both FT and ROC mode
“A=3845581634 B=880823580 C=1363937103 4 A=A-S B=B-C C=C-A A=A-B” \
IX86ver1.mpq \
IX86 \
W3XP \
“War3.exe 01/05/06 02:50:54 1572307” \
0x00000015 \
1.0.20.160 \
0x9130f661 \
W3XP_121a
从这里知道 为啥剑心的 登录不了，剑心的1.21 升级完毕 显示 1.0.20.160
正版 和 剑心 的版本信息都复制到 versioncheck.conf
得到下面的 信息，就OK 了， 删除 魔兽目录里面的 缓存 bncache.dat
