64, Issue 38 of Commodore Format magazine in November 1993 awarded the only 100% rating ever given to a Commodore 64 game in any major Commodore 64 publication. As no game had ever received such a high rating before, and as the commercial Commodore 64 scene was winding down in the mid-1990s, the awarding of 100% was seen as somewhat controversial. The game, titled Mayhem in Monsterland, was developed to exploit a multitude of programming tricks and quirks in the Commodore 64's hardware to the maximum. The impressive use of non-standard colors and scrolling resulted in perhaps the most graphically stunning game ever produced for the Commodore 64. The gameplay itself is similar to that of Nintendo's Super Mario Bros. and SEGA's Sonic the Hedgehog. Whilst mainstream commercial activity for games no longer exists for the C64, many enthusiasts and hobbyists still write games for the platform. In addition, a few small publishers still sell game software. Commodore 64 games continue to inspire developers and gamers on modern platforms such as iOS with many games being produced using similar styles of game-play mechanics to those from the Commodore 64 era. Type-ins, bulletin boards, and disk magazines Besides prepackaged commercial software, the C64, like the VIC before it, had a large library of type-in programs. Numerous computer magazines offered type-in programs, usually written in BASIC or assembly language or a combination of the two. Because of its immense popularity, many general-purpose magazines that supported other computers offered C64 type-ins (Compute! was one of these), and at its peak, there were many magazines in North America (Ahoy!, Commodore Magazine, Compute!'s Gazette, Power/Play, RUN and Transactor ) dedicated to Commodore computers exclusively. These magazines sometimes had disk companion subscriptions available at extra cost with the programs stored on disk to avoid the need to type them in. The disk magazine Loadstar offered fairly elaborate ready-to-run programs, music, and graphics. Books of type-ins were also common, especially in the machine's early days. There were also many books publishing type-ins for the C-64, sometimes programs that had originally appeared in one of the magazines, but books containing original software were also available. A large library of public domain and freeware programs, distributed by online services such as Q-Link and CompuServe, BBSs, and user groups also emerged. Commodore also maintained an archive of public domain software, which it offered for sale on diskette. Despite limited RAM
