2012 MTL patch for Popotan Po. Released via [url=https://web.archive.org/web/20190904063029/http://www.hongfire.com/forum/forum/hentai-lair/hentai-game-discussion/66139-popotan-po-translation-project-help-needed/page12]Hongfire Forum[/url] thread.
Barely readable, but logging just to record it / in case it helps anyone.
There was a project going on for a non-MTL patch (in the same thread) and people seem to have released both a tool to extract scripts and a partial patch, but I cannot find either to log these on VNDB for documentation.
