SLASH
SLASH (SuperLotsaAddedStuffHack) is a variant of NetHack 3.1.3, later updated to NetHack 3.2.2. It initially combined NetHack-- 3.1.3 with NetHack Plus. The subsequent addition of the Wizard Patch produced SLASH'EM.
Releases
Tom Proudfoot, who originally created NetHack-- 3.0.10, released six versions of SLASH:
SLASH 6 is archived at Ali Harlow's website here. Other versions may be found in various dusty corners of the Web.
NetHack 3.2.0 was released on 18 April 1996 and Tom Proudfoot released no more versions of SLASH. Enrico Horn later resumed development, releasing a SLASH based on NetHack 3.2.1 on 8 October 1996. The last version, called SLASH 4.1.2-8, was a merge with NetHack 3.2.2.
Enrico Horn's website has disappeared, but is still visible on the Wayback Machine here. The DOS source files are a pair of RAR files. They should be renamed without the "bin" suffix, as SlashSrc.rar and SlashSrc.r00; the Linux unrar program can then extract them. The sources are renamed in all caps, as is typical of MS-DOS file systems. Interested parties may prefer to download the Unix patch instead. This tarball should be unpacked into the top directory of a clean NetHack 3.2.2 source tree; it will unpack into new files and two patches. If only the first patch is applied, the resulting tree is in agreement with the DOS archive.
Legacy
The Wizard Patch proved popular, and in time Warren Cheung ported it to SLASH, calling the resulting game SLASH'EM, the EM part meaning Extended Magic. He released it on 7 January 1998. SLASH and SLASH'EM coexisted for the rest of the 3.2.2 era.
NetHack 3.3.0 accepted the Wizard Patch into the mainline code. SLASH'EM 0.0.5E8 merged in the 3.3.0 code, and consequently SLASH ceased to exist as a separate game from SLASH'EM.
