If you own a licensed WonderWitch cartridge, you may download the FreyaOS 1.2.0 update package on Qute's WonderWitch Player website. While the site is intended for WonderWitch Player owners only, this file also was available for registered WonderWitch owners via an FTP server; however, that server is no longer online.

Typically, these libraries were available on the WonderWitch and WonderWitch Player CD-ROMs, as well as on the WonderWitch registered user portal. While permission has been granted to redistribute them as part of games, many older releases do not include these libraries. Links to online copies of commonly required libraries are provided below:

• sound.il (1.02): http://wwgp.qute.co.jp/2002/entry/00058/rave/sound102.il
• bmpsaver.il (2.01): This library is used for development purposes only, but some games may accidentally depend on it. While the binary is not available online, source code for self-compilation is provided here http://wwgp.qute.co.jp/2001/entry/00152/BMPSaverWWGP
