However, since v2.2 SRB2 stores its resources in a PK3 file called srb2.pk3, which SRB2DB does not support. More crucially, SRB2DB expects the main resources for the game to be stored in a WAD file called the IWAD. However, these features are not necessary for mapping and do not harm SRB2DB's general functionality. Some SRB2DB-specific features, such as the FOF and zoom tube setup tools, no longer work correctly since v2.0. As a consequence, SRB2 Doom Builder was not updated to reflect the changes made to SRB2 from v2.0 onwards and no longer fully supports SRB2 mapping. Afterwards, Oogaland abandoned it in favor of an entirely new map editor, SRB2 Workbench. SRB2 Doom Builder was in development from 2006 to 2007. For a mapping tutorial for SRB2 Doom Builder, see the SRB2 Doom Builder tutorial.

An entirely rewritten and expanded version of Doom Builder has since been released as Doom Builder 2, which Zone Builder is based on. It is a modification of version 1.68 of Doom Builder that adjusts the editor for use with SRB2 and includes several additional features. SRB2 Doom Builder (abbreviated as SRB2DB) is a map editor for SRB2 v1.09.4 developed by community member Oogaland.
