Games like Squirrel King
Pikuniku
Pikuniku is an absurdly wonderful puzzle-exploration game that takes place in a strange but playful world where not everything is as happy as it seems. Help peculiar characters overcome struggles, uncover a deep state conspiracy, and start a fun little revolution in this delightful dystopian adventure!
Super Mario World
Super Mario World (超級馬里奧世界) is a bootleg port of the SNES launch title of the same name (Super Mario World) developed by Hummer Team and released in 1995. This is one of the more well-known examples of bootleg ports to the Famicom, as it comparatively manages to retain most of the original SNES game's elements.
Aladdin II
Aladdin II (not to be confused with the Sega Mega Drive pirate of the same name) is a pirated port of the official Sega Mega Drive version of Aladdin, made for the Famicom and released in mid-1995 by Chengdu Tai Jing Da Dong Computer Co.
Boogerman II: The Final Adventure
Boogerman II: The Final Adventure is an unlicensed port of the Mega Drive version of Boogerman: A Pick and Flick Adventure, made by Rex Soft in 1997. The gameplay is slow, and the controls are far less responsive than Super Game's version. There are 2 extra powers than what Super Game's version had: Belch and the Flame Gas ability (This power only works if pressing A, B, And Select all at once), but lacks garbage piles and the Milk Jug powerup. Also, it has two bosses removed from Super Game's version: FlyBoy and Revolta. The music in this version is more recognizable than Super Game's version. In the story intro, the text is scrolling up, instead of paragraphs, and lacks the animation of Boogerman cleaning the room. Super Game's version combines all four levels into one 1 Level each, but Boogerman II has only 2 of the four levels, separately, like Earthworm Jim 3 by Hummer Team, also made in 1997.
Boogerman
Super Boogerman is a Famicom port of Boogerman: A Pick and Flick Adventure, originally released for Sega Mega Drive and Super Nintendo. It was produced by Super Game and published by Realtec. The game is a recreation of the original Boogerman, but is considerably less faithful than Boogerman II: The Final Adventure, with a mixed-up level order and severely limited abilities for the player, which is compensated for by providing infinite ammo. Like many of Super Game's other bootlegs, this game has no ending; after the player defeats the third boss, the game merely resets.
AV Bishoujo Senshi Girl Fighting
AV Bishoujo Senshi Girl Fighting is a fighting game running on the Street Fighter II engine. It reuses a lot of resources from Street Fighter IV and Kart Fighter with some Master Fighter II stuff mixed in and most of the girls are based off of characters from Ranma 1/2 Chounai Gekitou-hen and Bishoujo Senshi Sailor Moon Fighting. Chun-Li in the game is from Street Fighter II: The World Warrior and Marry is Bunny from Street Fighter IV. You are awarded with hentai every time you beat a round when the difficulty is on 3, 4 or 5. These are backported from various PC98 H-games, such as Ten Sen Nyan Nyan.

Aladdin II
Aladdin II is an unlicensed Mega Drive port of the SNES version of Disney's Aladdin, originally made by Capcom in 1993. It might have been developed by ex-workers from Chuanpu Technology and was likely published by X Boy. This port can be considered the "opposite" of Aladdin 2000, a port of Virgin's Aladdin for the SNES.
Titenic
Titenic is a Famicom beat-em-up based off of the 1997 film Titanic by ex-Hummer Team members. This game was hacked to create the more well-known Harry's Legend. The game was most probably first known to be on an ABAB 3-in-1 multicart and was later found on a 15-in-1 separated into two separate games.
