original's "Magical Girl Mii" mini-game), new storyline content and routes based around Mii and Nono, a separate music CD containing background music from the original game, themed computer wallpaper, and desktop accessories. Some of the items must be unlocked. The fan disc preceded a re-release of the main game as Popotan Po! on August 1, 2003, as a DVD-ROM with game enhancements; it would be Petit Ferret's last official release. WellMADE produced a PS2 port named Oshiete! Popotan, released March 11, 2004. Scenes in the port were changed or removed to comply with Sony's ban on sexual content, but the release still warranted CERO 18 rating. Later, after the CERO revised its rating system, it was given a CERO D rating. WellMADE tried to compensate for their absence with graphics and gameplay improvements. WellMADE enticed buyers of the port with a bonus themed calling card, reversible poster, and music CD. WellMADE also released two free spinoff games in December 2003 and March 2004, collectively named and featuring Unagi as the heroine. WellMADE designed the games to be humorous and fun; the second allows Unagi to transform into her humanoid form after a certain point in the story. The initial limited edition release of Popotan on CD-ROM suffered critical errors, such as graphic display issues, saving and loading issues, the inability to complete some routes and Mii's mini-game not starting. Petit Ferret issued a patch on January 10, 2003. Later versions of the game were released bug-free. Issho ni A-SO-BO also contained several serious errors. Petit Ferret addressed these issues in two patches. The first patch added missing voice data from the original game CD; customers were given the option of downloading the patch or exchanging for a new CD. Ferret released the second patch on July 7, 2003; it corrected grammatical errors, adjusted the game's difficulty, and enhanced stability. The second patch did not contain the first's fixes.
