以下方法で過去ログ取得できたから一応参考に（※参考https://egg.5ch.net/test/read.cgi/software/1652118538/931-）

①https://egg.5ch.net/test/read.cgi/software/1649867583/3でgethtmldat.jsを作成、コマンドもリンク先で作成、gethtmldat.cfgは不要

②gethtmldat.jsの571行目に以下を追加

// ver 05.04.07
,{ "thr" : /<dl class="thread"[^>]*>.*\s*([\s\S]+?)(<\/dl>)/i
,"msg" : /[ \t]*<dt.*?>([0-9]+).+?(?:"mailto:(.+?)">)?<b[^>]*>(.*?)<\/b>(?:<\/font>|<\/a>)?(?: ?投稿日)? ?：(.*?)<dd>(.*?)(?:<br>)*(?=<dt.*?>|$)/img
,"rep" : "$1<>$3<>$2<>$4<>$5<>"
,"preReplace" : [ [/<\/?div[^>]*>.*(?=<dt|$)/ig, " "]
,[/<a href="(?:https?:)?\/\/.*?>([^<]*)<\/a>/ig, "$1"]
,[/(<a href=)"\/cdn-cgi\/l\/(email-protection\#.*?">)/ig,'$1"mailto:$2'] ]
,"postReplace" : [ [/<a href="javascript:be\(([^\)]+?)\)[^>]*>\?(.*?)<\/a>/ig, "BE:$1-$2"]
,[/<img src="(?:https?:)?(\/\/img\.[25]ch\.net\/.+?)">/ig, "http:$1"]
,[/<img src="(?:https?:)?(.*?)">/ig, IMG_TO+"$1"] ]
,"ln_terminate" : true
}

③gethtmldat.cfgがあるなら削除
