This game has a prototype article
Contra 4 returned the series to a handheld platform after 16 years, celebrating 20 years of the Contra franchise along with being a direct sequel to Contra III: The Alien Wars. Its Japanese subtitle even has a cutesy "DS" acronym like Advance Wars: Dual Strike.
Anything else you wanted? Sorry, no European version for you.
There are demo leftovers, check em out.
Document the menu.
By using Action Replay code 221C???? 00000006 where ???? is D850 (US) or E000 (JP) and restarting the game, a debug menu becomes accessible. This menu is very similar to the one in the leaked European prototype.
NOTE: Turn the cheat off before entering any of the options.
The most interesting selection in the debug menu is the GYM entry, a very preliminary stage featuring unused content. It is the only entry that sends you to a part of the game not accessible in regular play. Some interesting features (note that the Top Screen on the DS is actually blank in-game):
A different "Meat Puppet" enemy variant and a footsoldier with an incorrect palette.
Numerous interesting tidbits. A different gun turret; strangely, a piece of the weapon box tile from NES Contra; a different "Proboterror" enemy.
Winged angel enemies that shoot upwards.
A flame thrower enemy. One would imagine these guys would have been in the Laboratory stage (in the lab section), or in the start of the final level.
Present in the game are two graphic files which are most likely leftovers from early testing.
What appears to be early placeholder sprites from Operation C, as well as somewhat garbled soldier and player sprites. The background at the bottom is also an early cave background.
A simple image placeholder.
