Salio

Salio Inc. (サリオ株式会社) was the first third-party publisher to ever support a Sega console in Japan, being the only other company to publish games for the Sega Mark III besides Sega themselves. Until this point, Sega had published every cartridge and card in Japan, starting with the SG-1000 in 1983. Whereas Sega's Mark III and Master System games were labeled as "Gold Cartridges" in Japan, Salio's were labeled as "Silver Cartridges".

Salio was actually a dummy company created by Tecmo so they could circumvent Nintendo's exclusivity policy on third-party publishers and release games on competing platforms without repercussion. Salio's office was located at the Azumabashi district of Sumida, Tokyo, which was the location of Tecmo's original headquarters (back when they were known as Tehkan Ltd.) before relocating to Chiyoda in 1985. Only three games were published under the Salio brand: two on the Mark III and one on the PC Engine. Tecmo would publish games on later Sega platforms under their own name after Nintendo became less restrictive on third-party supporters.
