Don Puchi was a mobile-based 'port' of Don Pachi and was released in 2003. This was issued on 504i series cell phones

As mobile hardware has changed drastically, I haven't much information here. However, long ago I pulled some screenshots from Cave's official site (original mobile pages are long gone).

You can read an old news blip in Japanese from 2003 over at K-Tai Watch where it was announced.
