Ever stumbled across one of those weird Japan-only NES games that make you go, "Wait, what is this?" That's Datach - Yuu Yuu Hakusho for you. It's based on the classic anime, but instead of a straight-up fighter or RPG, it's this bizarre hybrid where you collect cards (using this old-school barcode scanner peripheral Japan loved in the '90s) to summon characters and battle.

First time booting it up, you're hit with that crunchy NES soundtrack and pixel art of Yusuke and the gang—total nostalgia trip if you grew up with the anime. The actual gameplay? Kinda janky, honestly. You scan cards to call in special moves or characters, but without the scanner, you're stuck with whatever the game gives you. Still, there's something charming about how ambitious it was for the time.

Not gonna lie, it's more of a novelty than a must-play, but if you're deep into Yuu Yuu Hakusho or weird retro oddities, it's a fun little time capsule. Just don't expect it to hold up like the better-known NES classics.
