Editing Chip's Challenge (section)

==Development==
In 1989, Sommerville led a team of programmers at Epyx to write ''Chip's Challenge'' for [[Atari Lynx]] during a ten-week period shortly before the system's launch.<ref name=orland/> Sommerville had developed a crude prototype of the game on an [[Apple II]] to develop the game's logic and to demonstrate to Epyx that it would be fun. Sommerville designed about a third of the levels, Bill Darrah designed another third, and the rest were developed by other Epyx staff.<ref name=chuck_note/>

''Chip's Challenge'' was ported to several other systems, including the [[Atari ST]], [[Amiga]], [[Commodore 64]], [[ZX Spectrum]],<ref>{{cite web|url=http://www.worldofspectrum.org/infoseekid.cgi?id=0000937 |title=Chip's Challenge |publisher=World of Spectrum |access-date=2014-06-21}}</ref> [[MS-DOS]], and [[Microsoft Windows|Windows]]. Most of the conversions from the Atari Lynx original to other formats were carried out by [[Climax Studios|Images Software]] in the [[United Kingdom|UK]], except for the Microsoft Windows version.

Microsoft licensed ''Chip's Challenge'' from Epyx for a Windows 3.1 version of the game, developed by Microsoft under the direction of [[Tony Garcia (video game producer)|Tony Garcia]].<ref name=chuck_note/> It was coded by Tony Krueger, with artwork by Ed Halley.<ref>[[About box]] from the game</ref> Entering "TONY" as a password will bring the player to a level that credits the "[[Microsoft Entertainment Pack|WEP]] 4 test team" in the hint for that level and also contains different tiles that spell out developer names, including Doug T., Rob D., Ed H., and Lisa F.<ref>Level 145 ("Thanks to...")</ref> According to Doug, a former roommate of Krueger's and one of the testers for the game, it was written in a single summer.<ref>{{cite web|url=http://www.abandonia.com/vbullet/showpost.php?p=223121&postcount=45|title=Forums - View Single Post - Chip's Challenge|website=www.abandonia.com|access-date=28 November 2018}}</ref>

The Microsoft version was included in the fourth ''[[Microsoft Entertainment Pack]]'' and ''[[Best of Microsoft Entertainment Pack]]''. This version had significantly different sound and graphics, but became very popular due to the success of the Microsoft Entertainment Pack. The sequel, ''Chip's Challenge 2'' would be based on this version.

[[Bulletin board system|BBS]] and early Internet forums dedicated to the Microsoft version allowed users to share home-made level editors and unofficial expansion packs, which was an early example of software [[Mod (video gaming)|modding]].<ref name=orland/>
