Family Basic V3 is a game creation cartridge for the Nintendo Family Computer / Nintendo Entertainment System.

Family BASIC is an accessory for the Family Computer (Famicom) created by Hudson Soft, Nintendo, and Sharp Corporation. It allowed users to create programs in the BASIC programming language, more specifically the NS-HuBASIC language which stands for Nintendo, Sharp, and Hudson Soft respectively. This accessory came with a specially designed cartridge and keyboard, similar in function to that of a Commodore computer of that era. There was also the Data Recorder peripheral which was sold separately. It was preceded by the nearly identical Playbox BASIC for the Sharp C1 Famicom TV. Family BASIC V3 was released on February 21, 1985 as a stand-alone cartridge.


The Playbox BASIC and Family BASIC were both released in 1984 and came with NS-HuBASIC v1.0. Their initial retail price was the same as the Family Computer. V1.0 cartridges are now rare and Playbox BASIC ones are extremely rare as the only people who bought it were owners of the expensive C1 TV sets.

Family BASIC V3 was sold as a separate title with NS-HuBASIC v3.0 in red cartridges. It was marketed to people who already owned a previous version so it did not come with a keyboard and its manual served as an addendum to the previous v2.x manual. As a result of its narrow market, it sold poorly and is now rare. Unlike the previous versions, it did away with the message, calculator, and music boards to concentrate solely on programming. It had double the RAM capacity and came with pre-programmed mini-games.

Many of the sprites and tilesets were taken directly from the Arcade Classics Series version of the Donkey Kong, Donkey Kong Jr., and Mario Bros. There are 16 animated sprites built-in. There are four sample games and instructions on making others.

There are imposters among us! Find them. Mark them. Stop them before they kill the entire crew of this spaceship.

The Tragedy of Ryohyukan (Ryuuhyoukan no Sangeki) is a 1993 NES/Famicom minigame programmed in Famicom Family BASIC V3 by Takashi Endo and published over three pages of the magazine "Micom BASIC (マイコン BASIC)" in early 1994.

Graphics and text have been changed in this version to translate the minigame from Japanese, and reflect the 2018 PC game Among Us, by Innersloth, Marcus Bromander and Forest Willard.


There is a group of red crewmates on the screen and your job as detective is to find the imposter killer(s) and mark them pink/purple.

Press A to change the movement direction of the crewmates currently standing still, and split them up.

Press B to mark all the crewmates standing still as killers, or unmark them.

Press Start to see if you’ve marked all the killers (and just killers) pink/purple.

If you did, a little devil marker appears above their head(s) and you win the stage.

You get points for living crewmates and bonus points for speed.

There is a timer in the upper right corner with pink rectangles that disappear over time. If you run out of pink rectangles, you lose. If the killers kill all the innocents, you lose. You can lose up to 3 times before it resets you back to the main screen.

You start with 1 out of eight crewmembers as an imposter. The imposters will increase in number and the crewmates decrease in number.

You can use the left/right and up/down D-pad arrows on the title screen to choose number of crewmates and game speed (low/high). A completed game will include all amounts of crewmates between 4 and 8.
