Delbert the Hamster Software
From IFWiki
Delbert the Hamster Software was a publisher of ZX Spectrum games that operated between 1991 & 1992.
The label was run by adventure author Scott Denyer and it published his own original games, collaborations with others (such as Gareth Pitchford and Richard Ng), and a selection of re-releases from the likes of Zodiac Software, Graham Burtenshaw, and Global Games.
Authorised ports of Delbert the Hamster games were published for the Commodore C64 and/or Amstrad CPC by The Guild Adventure Software and The Adventure Workshop.
When Delbert the Hamster Software closed down in 1992, many of its games went on to be republished by Zenobi Software.
