C-So!

C-So! (sometimes referred as C_So! or C-SO!) is an action game, developed by Compile (under license from Pony) and released by Sega for in 1985. The game was released on SG-1000 and requires the Card Catcher to be played in SG-1000, SG-1000 II, SC-3000, Othello Multivision and/or SD-G5, as the game itself was released only in Sega My Card format. As with most Compile games, C-So! is currently owned by D4 Enterprise.

In this game, players control a warehouse employee named Comy to protect valuable items from the monsters of the Warugaki gang, who wants to steal them. To defeat them, Comy can defeat them by jumping on them with a see-saw. A stage editor is also available, allowing players to make their own stage and save their creations with the SR-1000 data recorder connected through the SK-1100 keyboard on SG-1000 or directly into the SC-3000.

Aaronix brought C-So! to Taiwan in standard SG-1000 cartridge format somewhere in the 80s. Joy Soft brought the MSX version to SG-1000 as well, as an unlicensed release in South Korea.
