To commemorate this, Sega re-released Thunder Force III in 3D as part of Sega 3D Fukkoku Archives 3: Final Stage ( Sega 3D Classics Collection 3) for the Nintendo 3DS. In September 2016, at the Tokyo Game Show, Sega announced that they owned all the intellectual property rights from Technosoft. However, with the announcement of Thunder Force VI, the copyright for the game has been apparently turned over to one of the series' creators and may no longer apply. However, as of January 2008, no updates other than 'We will restart soon! Please wait for a while.' and 'THUNDERFORCE is a registered trademark.' have been added to the website.

In 2006, the URL was registered and updated. After Technosoft ceased game development in 1999, also some staff left and start another game development company, Ganbarion. Team Raimon later became a new independent game development company, CA Production in 1993. Some Technosoft staff left to found a development team named Team Raimon, at Red company, and developed Gate of Thunder and Lords/Winds of Thunder. Technosoft ceased game development in 1999 and defunct in 2001, and merged as R&D division of it's associated company, Twenty-one Company. After Thunder Force IV, They built a new office building at 165-1, Katsuumi-cho(勝海町) and moved in March 1993. In April 1982, Sasebo mycom center is moved to 4-14, Fukuishi-cho(福石町), converted to a limited company and renamed to Technosoft. Founded by Ohzono Tomio in February 1980 at 2-15, Minato-cho(湊町) as Sasebo mycom center, and moved after to 2-8, Matsuura-cho(松浦町). Given the… closeness of the game title and company name, I think TechnoSoft was specifically aiming to confuse people into thinking that this was a Kunio game, but it’s not.It was located at city of Sasebo(佐世保), at Nagasaki prefecture. It deserves some playtime though, even if the lack of Kunio is a bit of a disappointment. As it is, the amount of bizarre doesn’t quite reach the level of Gourmet Sentai Barayarou for the SNES, with its nose-rocket-propelled moai heads and dance button, but it comes sort of close, with half of the second level being inside a whale (which eats you at the end of the first.) Inside the whale you’ll find boxing octopi and blobs of water with “H2O” written on ‘em. In fact, the whole thing just screams of average, and it would remain so if it took itself seriously. The sound is, as well, nothing to write home about. Graphically, the game is… well, sub-par for the Playstation, but considering that it was one of the first titles to grace the system (and considering that it was up against the likes of Funky Horror Band for Sega CD as a contender for “worst near-launch title graphics”) I’d say it did quite well. You’ve got your three characters, the big buff slowpoke, the fast but weak girl, and the all around average guy, and they walk through a bunch of levels beating the puss out of stuff for some reason or another. Nekketsu Oyako by TechnoSoft (or alternately Tecno Soft) – not to be confused with the other Nekketsu games, starring Kunio, by Technos – is a rather average Final Fight clone beatemup.
