King's Valley

King’s Valley is a platform/maze game from Konami, released for the MSX computer and MS-DOS in 1985. The game plays is like Lode Runner except it takes place in pyramids instead of Egyptian ruins. As an intrepid adventurer, the player's goal is to collect various gems, while evading angry mummies and other monsters long enough to find the exit to the next level. A port to MS-DOS was made by a Korean company named APROMAN, however it only supports monochrome and CGA graphic cards. Another unofficial port has been released by the Spanish RetroWorks [1] in 2009 for the ZX Spectrum on the site 'World Of Spectrum'[2]. The MSX version of this game can still be run with emulators like BlueMSX [3]. Emulators for the Sinclair ZX Spectrum are available at WOS. King's Valley had been rewritten (not ported or emulated) in 2008 using Java, Online version is playable over internet using the web-browser and Mobile version is downloadable for handhelds, mobiles and communicators with Java installed for personal use [4].

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.

Felix the Cat is an unlicensed platform game developed and published by Dragon Co. in 1998. It is unrelated to Hudson Soft's official Felix the Cat title, released in 1992, but the gameplay of the two games is very similar.

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.

Squirrel King is an unlicensed platform game developed for the Sega Mega Drive. It was published and developed by Gamtec, and therefore its origin is Taiwan. Squirrel King is extremely similar to Capcom's Chip 'N Dale: Rescue Rangers and it sequel, Chip 'N Dale: Rescue Rangers 2 for the NES, to the point where the player actually plays as two characters named "Chip" and "Dale" (though they look slightly different to their Disney counterparts). C jumps, B picks up and throws crates, and A allows Chip or Dale to throw fireballs, assuming they have some in their inventory. Squirrel King is the basis for another unlicensed title, Super Mario World, also for the Mega Drive,but developed by Chuanpu and possibly published by Ming Super Chip Electronic.

This port can be considered the "opposite" of Aladdin 2000, a port of Virgin's Aladdin for the SNES.
