Question: What did the publisher of Battle Clash rely on for its support?

full_context: Document 1: Nintendo Entertainment System: Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.
Document 2: Super Nintendo Entertainment System: The company continued to carefully review submitted titles, giving them scores using a 40-point scale and allocating Nintendo's marketing resources accordingly. Each region performed separate evaluations. Nintendo of America also maintained a policy that, among other things, limited the amount of violence in the games on its systems. One game, Mortal Kombat, would challenge this policy. A surprise hit in arcades in 1992, Mortal Kombat features splashes of blood and finishing moves that often depict one character dismembering the other. Because the Genesis version retained the gore while the SNES version did not, it outsold the SNES version by a ratio of three or four-to-one.
Document 3: NRA Gun Club: NRA Gun Club ("Gun Club in Italy") is described as a nonviolent first-person target shooting game by Crave Entertainment in North America and 505 Games only in Italy (Although a German release was planned, but cancelled for unknown reasons). The game allows gamers to enter the shooting range and shoot at paper targets, watermelons and sporting clays. The game contains over 100 licensed and recreated firearms.
Document 4: Nintendo Entertainment System: By 1988, industry observers stated that the NES's popularity had grown so quickly that the market for Nintendo cartridges was larger than that for all home computer software. Compute! reported in 1989 that Nintendo had sold seven million NES systems in 1988, almost as many as the number of Commodore 64s sold in its first five years. "Computer game makers [are] scared stiff", the magazine said, stating that Nintendo's popularity caused most competitors to have poor sales during the previous Christmas and resulted in serious financial problems for some.
Document 5: Nintendo Entertainment System: As the 1990s dawned, gamers predicted that competition from technologically superior systems such as the 16-bit Sega Mega Drive/Genesis would mean the immediate end of the NES’s dominance. Instead, during the first year of Nintendo's successor console the Super Famicom (named Super Nintendo Entertainment System outside Japan), the Famicom remained the second highest-selling video game console in Japan, outselling the newer and more powerful NEC PC Engine and Sega Mega Drive by a wide margin. The console remained popular in Japan and North America until late 1993, when the demand for new NES software abruptly plummeted. The final Famicom game released in Japan is Takahashi Meijin no Bōken Jima IV (Adventure Island IV), while in North America, Wario's Woods is the final licensed game. In the wake of ever decreasing sales and the lack of new software titles, Nintendo of America officially discontinued the NES by 1995. However, Nintendo kept producing new Famicom units in Japan until September 25, 2003, and continued to repair Famicom consoles until October 31, 2007, attributing the discontinuation of support to insufficient supplies of parts.
Document 6: BattleSport: BattleSport is a 1996 futuristic sports video game developed by Cyclone Studios. It was originally published by Studio 3DO (the software division of The 3DO Company) exclusively for their 3DO Interactive Multiplayer in 1996, but after the 3DO was discontinued "BattleSport" was published for other systems by Acclaim Entertainment. It was released for Windows and PlayStation in North America on June 30, 1997, and in Europe on August 1, 1997. It also saw a US only release on the Saturn.
Document 7: Brawl Brothers: Brawl Brothers, known in Japan as , is a side-scrolling beat 'em up game developed and published by Jaleco for the Super Nintendo Entertainment System in 1992. It is the second game in the "Rushing Beat" series, after "Rival Turf!", and was followed by "The Peace Keepers" in 1993.
Document 8: Cannon Spike: Cannon Spike, originally released in Japan as , is a multi-directional shooter arcade game released in 2000 by Psikyo and later in the same year for the Dreamcast by Capcom. It uses Capcom-designed characters and runs on Sega's Naomi Hardware. "Cannon Spike" is similar to games like "Smash TV" and Capcom's "Commando", although with primary focus on boss fighting. "Cannon Spike" is noted as one of the last games released for Dreamcast in Europe, published by Bigben Interactive and exclusively sold at retail in Game outlets.
Document 9: Nintendo Entertainment System: Atari Games created a line of NES products under the name Tengen and took a different approach. The company attempted to reverse engineer the lockout chip to develop its own "Rabbit" chip. However, Tengen also obtained a description of the lockout chip from the United States Patent and Trademark Office by falsely claiming that it was required to defend against present infringement claims in a legal case. Nintendo sued Tengen for copyright infringement, which Tengen lost as it could not prove that the legally obtained patent documents had not been used by the reverse engineering team. Tengen's antitrust claims against Nintendo were never finally decided.
Document 10: Nintendo Entertainment System: In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.
Document 11: Sea Battle: Sea Battle is a multiplayer strategy game released by Mattel for its Intellivision video game system in 1980. In the game, players command fleets of naval vessels attempting to invade the harbor of their opponent.
Document 12: Nintendo Entertainment System: The Nintendo Entertainment System (commonly abbreviated as NES) is an 8 - bit home video game console that was developed and manufactured by Nintendo. It was initially released in Japan as the Family Computer (Japanese: ファミリーコンピュータ, Hepburn: Famirī Konpyūta) (also known by the portmanteau abbreviation Famicom (ファミコン, Famikon) and abbreviated as FC) on July 15, 1983, and was later released in North America during 1985, in Europe during 1986 and 1987, and Australia in 1987. In South Korea, it was known as the Hyundai Comboy (현대컴보이 Hyeondae Keomboi) and was distributed by SK Hynix which then was known as Hyundai Electronics. The best - selling gaming console of its time, the NES helped revitalize the US video game industry following the video game crash of 1983. With the NES, Nintendo introduced a now - standard business model of licensing third - party developers, authorizing them to produce and distribute titles for Nintendo's platform. It was succeeded by the Super Nintendo Entertainment System.
Document 13: Nintendo Entertainment System: In the longer run, however, with the NES near its end of its life many third-party publishers such as Electronic Arts supported upstart competing consoles with less strict licensing terms such as the Sega Genesis and then the PlayStation, which eroded and then took over Nintendo's dominance in the home console market, respectively. Consoles from Nintendo's rivals in the post-SNES era had always enjoyed much stronger third-party support than Nintendo, which relied more heavily on first-party games.
Document 14: Nintendo Entertainment System: A variety of games for the FDS were released by Nintendo (including some like Super Mario Bros. which had already been released on cartridge) and third party companies such as Konami and Taito. A few unlicensed titles were made as well. However, its limitations became quickly apparent as larger ROM chips were introduced, allowing cartridges with greater than 128k of space. More advanced memory management chips (MMC) soon appeared and the FDS quickly became obsolete. Nintendo also charged developers considerable amounts of money to produce FDS games, and many refused to develop for it, instead continuing to make cartridge titles. Many FDS disks have no dust covers (except in some unlicensed and bootleg variants) and are easily prone to getting dirt on the media. In addition, the drive use a belt which breaks frequently and requires invasive replacement. After only two years, the FDS was discontinued, although vending booths remained in place until 1993 and Nintendo continued to service drives, and to rewrite and offer replacement disks until 2003.
