For many years, this caused confusion among fans of the DWANGO series. Falconer, a former DWANGO moderator, had long maintained that no such WAD existed on his RareFiles site, however no explanation was given as to why, leading some to doubt this claim.
In September 2020, Doomworld user Shockwav3 started a thread to further investigate whether or not a true DWANGO9 had ever existed. When searching through an archive of old DWANGO files posted by former moderator HDrambo, he discovered a file called DWANGO!.WAD, which had DWANGO9 textures present in two different maps, strongly hinting that the WAD had existed at some point.
In October of 2021, former DWANGO moderator Voyager7 got in touch with Doomworld user Doomkid after a watching a video he had created on the topic of DWANGO9. Shortly thereafter, Voyager7 posted in the , confirming that DWANGO9 had never been finished, and that the files "DWANGO!.WAD" and "BLUDBATH.WAD" were both originally contenders for the DWANGO9 title. Voyager7 speculates that, as the Dallas DWANGO server had already created and published DWANGO10, it made little sense to release DWANGO9 later on, resulting in him renaming the WADs he had initially planned to be DWANGO9, leaving a permanent gap in the series.
- DWANGO8 and DWANGO10 have last modified dates of March and August of 1996 respectively, however Voyager7 has confirmed that DWANGO9 was still not complete even after DWANGO10 had initially been released.
- Voyager7 continued to periodically modify the map that was intended to be the starter for DWANGO9 well into the 2000s for LAN parties and to add some source port features. The WAD can be found at , called "Beta4ev.wad", contained alongside the other WADs that almost received the DWANGO9 title.
