throughout the decade. In addition to distributing games from other manufacturers across the country, Hoei Sangyo also began production of its own games in-house, the majority being clones of other popular games like Space Invaders. Matsusa's business established a relationship with Esco Trading, a company formed by Sega president Hayao Nakayama, which gave the latter the rights to distribute Hoei Sangyo's video games to other parts of Japan. Hoei Sangyo released its first original video game in 1981, Jump Bug, an early side-scrolling platform game released outside Japan by Rock-Ola. Hoei Sangyo was reorganized into Coreland Technology Inc. in June 1982, where it became a contractor company that developed games for other games. One of its first projects was Pengo, which was released the same year by Sega. Pengo was successful arcades and lead to several sequels and home conversions. Coreland also designed games such as 4-D Warriors and I'm Sorry for Sega, and Black Panther for Konami. In the late 1980s, Coreland established a partnership with toy company Bandai, known for its model kits and action figures based on popular characters like Mobile Suit Gundam. At the time, Bandai was suffering from numerous financial difficulties as a result of the slumping Japanese toy market affecting the demand for its products. Coreland's positive track record was the primary reason for the partnership, as Bandai hoped it would allow itself to secure a stronghold in the coin-op industry. However, Coreland was undergoing its own financial constraints, having accumulated more than 1.5 billion in debt due to poor sales. As contractual agreements prevented Bandai from backing out of its deal, it chose to majority-acquire the company in February 1989. Coreland was reorganized again into Banpresto; the name came from a portmanteu of "Bandai" and "presto", a word used to describe magic. Yukumasa Sugiara, a member of Bandai's board of directors, became the company's president. Super Robot Wars and expansion (1989–1996) Banpresto underwent significant changes as a result of Bandai's acquisition of the company. With Banpresto becoming Bandai's arcade game division, Banpresto was given the exclusive rights to use Bandai-owned characters for video arcade games and children's rides. It was also allowed to produce games for home video game consoles, such as the successful Nintendo Family Computer (Famicom); Banpresto received strict orders to not release any games that could compete with those from Bandai. One of the company's first projects was SD Battle
