Just noticed this site is using the same base code of Tinychan

https://chan.mx/
https://chan.mx/kareha.php
https://chan.mx/vich.php

After skimming the HTML and noticing some parallels (links, @citations, etc.), it looks like the Mexican site is running a modded Tinychan-based engine.
Does anyone know where the source code is hosted?
