Happy Biqi III - World Fighter (C)-2

Happy Biqi III: World Fighter's gameplay.

Unlike other NES ports of Earthworm Jim 2, this one uses a a regular kid (by the name of Biqi) as the main character instead of Jim.

The stage included in this port are: Wood Hills (Anything But Tangerines), Water Monster Tunnel (Villi People), Flight (The Flyin' King), Farm (Udderly Abducted), Mine (Inflated Head), Electric City (See Jim Run, Run Jim Run), and Puppy Love stages.

Compared to Earthworm Jim 2, presumably due to memory limitations, the maximum ammo is 255 bullets. The movement is somewhat slow in Water Monster Tunnel, compared to the original or other ports which move at a very fast pace.

All music used in this game is Waixing's original work, except the Puppy Love music which uses a rendition from the original game (being a variation of Tarantella Napoletana, the examples of use of which include Gioachino Rossini's "La Danza" from Soirées Musicales (1830–1835)).

After completing a level, a scene showing Biqi and the princess appears, and in both versions the credits are in Chinese.


  • The single-cart version features a battery which can save the progress (by pressing Start during gameplay and then choosing the first option). This was removed in the multicart releases, as pressing Start does nothing.
  • In the single-cart version, there's a difficulty option (Easy, Medium and Hard) and the starting lives are 9, 5 and 2 respectively. However, it doesn't affect the amount of damage the player can get.
  • Despite being developed in China, The text in this game is a mix of Simplified and Traditional Chinese, a common trait in Waixing's earlier games.
  • The font used for this game is from ETen Chinese System (倚天中文系統). This font is also used in many old Taiwanese video games (notably DOS games) and other early Waixing games.
  • The re-release version's box is stolen from Dos game Mo jing Da Mao xian (魔境大冒險).
