| Konami's MSX cartridge of TwinBee, RC740, prints "© Konami 1986" on its box and booklet. The box says it runs on every MSX computer, for one or two players, with joystick or keyboard, and that the instructions are in English, French, German, Spanish and Italian. | image 1, booklet cover | Publisher |
| The MSX booklet's story, set far in the future: the Spice King's army overruns Paradise Island and takes its Jewel, which falls to him and his four Shogun henchmen. The islanders' hope is the reclusive Dr. Cinnamon in the Valley of the Unknown, who has built two rocket-powered fighters, Winbee and Twinbee, for his two sons to fly. | p. 1 (image 2), STORYp. 1 (image 2)p. 1 (image 2)p. 1 (image 2) | Manual |
| On the MSX, one player or two at once play as a team. A fighter has a single-barrelled cannon and bombs. Play starts with three fighters and gives another for every 100,000 points, up to 99. Crashing into an enemy loses a fighter; a hit from a projectile loses the bomb-launching arm, and a second hit without it destroys the fighter. A lost arm can be replaced once, by docking with a passing rescue vehicle. The score isn't shown during play; F1 shows it and pauses. | p. 2 (image 3), 1.

| The MSX booklet lists the bells as yellow for bonus points, blue for speed, white for a double cannon, green for the Doppel-Ganger Effect (one player only) and red for a force field; shot too often, a bell turns black and destroys a fighter that touches it. Ground targets leave cherries (bonus points), Super Candy (triple shot, one player only), Crash Stars (clearing the screen of enemies and their shots) and Miracle Milk (an extra fighter). A fighter can't have the force field and the Doppel-Ganger at once, and two players get neither the Doppel-Ganger nor the triple shot. | p. 3 (image 4), 2.

| On the MSX the game takes a joystick or the keyboard. In single play the cursor keys move the fighter, trigger A or the space bar shoots, and trigger B or the M key activates bombing; in double play the second player's keys are E, C, F and S to move, CTRL to shoot and TAB to bomb. F1 shows the score and pauses. | p. 4 (image 5), 3.
