Digital Monster Version 1 Yellow Design. - Color: Yellow - Design: Block pattern - Function: Digital pet - Country of origin: China Thank you for looking. Released in 1997. I played it for the first time in about 25 years, and it still works normally. As of March 13, 2026, I have been playing it for 9 days. As of March 19, 2026, I have been playing it for 15 days (see 4th image). Since it has been a long time since its release, I cannot guarantee its operation after it reaches you. Therefore, please only purchase if you understand this. No claims, no returns. Batteries will be removed before shipping. I am also selling Version 1, Version 2, and Version 3, so bulk purchases are also possible.
