D4 Enterprise was founded on March 3, 2004, by former Bothtec Inc. employee, Naoto Suzuki. Suzuki had previously been involved with the creation and management of Project EGG - and D4 Enterprise was created in part due to declining interest in the running of that service on the part of Bothtec. In November 2004, D4E would launch a sub-section of Amusement Center called the "iTa-Choco Shop". The iTa-Choco Shop was a store focused around games by iTa-Choco Systems - the personal company of Kōji Sumii (also known by the
pseudonym, Rasho), the creator of
Bokosuka Wars. The iTa-Choco Shop was terminated on May 10, 2022. D4E would also launch another sub-section of Amusement Center called "Compile Station", dedicated to the works of former game publisher
Compile. A selection of 40 free''
Compile games and a Madō Monogatari''
4-koma webcomic drawn by Compile illustrator "Ichi" are available via Compile Station. D4 Enterprise continued to jointly operate Soft-City.com, even after Bothtec divested their stake in the service to Gaiax Co. Ltd in early 2005. from over 100 different composers - including works by
Ryu Umemoto and
Yuzo Koshiro. 150 titles were released on the service, with games from the
Famicom,
Super Famicom,
PC Engine and
MSX available. i-revo games was discontinued on March 31, 2011. In August 2006, D4 Enterprise would announce their involvement with creating and distributing the
1chipMSX - a special miniature recreation of the
MSX2, first shown off in October 2004 and originally created as a collaboration between
ASCII Corporation and the MSX Association.'''' The 1chipMSX would later be exhibited by D4E at
Tokyo Game Show 2006, and pre-orders were opened on October 12, 2006. 1chipMSX finally released on December 11, 2006. Only 5000 units of the device were produced, with the last units being sold in a special campaign celebrating the 25th anniversary of the original MSX - in 2008. There were originally plans for Dutch manufacturer Bazix to distribute the 1chipMSX in
the West, as the representative of the MSX Association outside of Japan; however licensing difficulties, disagreements between the involved parties and the transfer of the MSX trademark from MSX Association to MSX Licensing Corporation resulted in Bazix terminating their working relationship with MSX Association and 1chipMSX was never released outside of Japan. On December 29, 2006, another sub-section of the Amusement Center site was opened - Falcom Museum, a service for distributing older
Nihon Falcom titles and for compiling information related to all Falcom titles at the time. These older Falcom titles also became available on Project EGG at the same time. In 2007, D4E would establish a
record label called EGG Music Records, to distribute physical editions of EGG Music albums. To date, over 30 physical albums have been released under the EGG Music Records imprint. On September 18, 2007,
Neo Geo titles started to become available on the
Wii's Virtual Console service in
Japan - provided by D4 Enterprise, distributing titles under licence from
SNK Playmore. – although both would later be delisted in 2012. D4E would also distribute 13
Konami MSX titles for Wii Virtual Console in late 2009 and early 2010. and the Wii U Virtual Console was discontinued on March 27, 2023. D4E started releasing apps for iOS in December 2008, starting with ports of old MSX games (including
Aleste,
Zanac and
Nyanpi) but eventually also including original titles such as
Jellyfish ip and
Hachiko Guru Logi Coupon - the latter of which also receiving an
Android port in 2013. On December 2, 2009,
Snapdots (a reimagining of the 2001
Game Boy Advance title
Guru Logi Champ by
Compile) was released for
DSiWare. In 2017, D4E would announce and release
EGGY, a special version of Project EGG for the
Yahoo! Games Game Plus service.
IP Acquisition D4 Enterprise has acquired the rights to the
intellectual property (IP) of several Japanese games companies including from several that have gone out of business, with the intent to preserve their libraries and ensure that people can still enjoy their works. Their first acquisition came in November 2005, D4E would later enter a licensing agreement with
Compile Heart in 2010, allowing the latter company to use Compile's IP to create new titles. However, neither of these two agreements involved the
Puyo Puyo franchise, as Compile had sold the rights for
Puyo Puyo to
Sega in 1998. In October 2006, D4 Enterprise announced that it had negotiated a transfer of rights from BBMF Group Inc. for the library of Bothtec, Inc - the company that originally started Project EGG, and where D4E CEO Naoto Suzuki worked before he founded D4E. In 2010, D4E acquired the rights to the 1988
Data East game
RoboCop - based on the
movie of the same name. The IP rights to the library of
HummingBirdSoft (including
Laplace no Ma and the
Deep Dungeon series) were acquired by D4 Enterprise in March 2013. and later acquired the rights to the entire game libraries of both companies on March 4, 2019. By this time, D4E had also acquired the rights to the libraries of Cosmos Computer,
System Sacom, Carry Lab and Winkysoft. However, D4E did not have access to the games and promotional materials to start distributing the titles on any of their services; so D4E also announced a
crowdsourcing campaign to help preserve the game materials. == Games and products ==
