Karnov is a 1987 platform arcade game. It is the debut of Data East's mascot of the same name. After Data East became defunct due to bankruptcy in 2003, Paon, a company comprising former Data East staff, acquired the rights to Karnov, along with multiple other Data East games. In the game, players take control of the title character Jinborov Karnovski, or "Karnov" for short. Karnov is a strongman popularly illustrated as being from an unspecified part of the Soviet Union's Central Asian republics as shown on the original arcade flyer and again in Karnov's Revenge.

KIRA KIRA STAR NIGHT is an action game created by renowned manga artist and illustrator RIKI. From the graphics, sound to the game’s programming, an all star cast of creators have joined together to make this 8-bit tour de force that has been released over a number of formats. Now, KIRA KIRA STAR NIGHT exa comes to the arcade in pixel perfect aspect ratio form with even faster response times than the NES original at a special price point. For the first time ever, play the game at 4K in both horizontal and vertical screen orientations.

Kira Kira Star Night AC is an arcade adaptation of Kira Kira Star Night DX created to promote the release of its console cousin. It plays almost exactly the same: players take on the role of Fami-chan, catching falling stars to try and achieve a high score. The gameplay in this version is slightly tweaked, with Fami-chan now having two different jump heights based on the jump button the player chooses. It had a limited release of one cabinet at the Kaden no Ken-chan store in Akihabara before later being released on CD-ROM for Windows.

Kira Kira Star Night DX follows Fami-chan. She’s a young woman jumping around environments, attempting to catch stars while chiptunes play in the background. The goal is to get a certain number of stars before time runs out. There are nine stages total, and the game features music from Takeaki Kunimoto, Yuriko Keino, Yuzo Koshiro, Nobuyuki Koshiro, Tappy, Manami Matsumae, Hally, Bun, Robokabuto, Yasuhisa Watanabe, and Takeshi Yokemura.
