Retro Game Challenge

Retro Game Challenge (a.k.a. Game Center CX: Arino's Challenge) is a Nintendo DS game based on the Japanese TV series Retro Game Master. In the game, your character is pulled back in time to The Eighties and the childhood of one Shinya Arino (based on the host of the show himself), and are tasked with meeting the challenges of his evil-self-from-the-present by playing eight different 8-bit games, which emulate the style of actual Family Computer games of that time. Only then will you be able to return to your own world.

Each of the eight mini-games comes with its own fully colored and illustrated (in-game) manual, and Kid Arino will periodically buy game magazines that contain cheat codes (which you are allowed to use against his future self) that you can browse while playing.

Absolutely no marketing in America led to poor sales, which means that XSEED didn't bring the sequel to America. But have no fear: a Fan Translation is in the works.

Styles emulated by the mini-games:

 * Driving Game: Rally King and Rally King SP.
 * Platformer: the Robot Ninja Haggle Man trilogy (the first two are based on a Japan-only Jaleco game titled Ninja Jajamaru-Kun, while the third is a Ninja Gaiden pastiche).
 * Role Playing Game: Guadia Quest (heavily based on Dragon Quest, even having the menu you need to bring up to talk to people)
 * Shoot'Em Up: Cosmic Gate (modeled after Galaga) and Star Prince (a pastiche of Star Soldier).

Cosmic Gate provides examples of:

 * Asteroid Thicket / Bonus Stage
 * Big Creepy-Crawlies / Bug War
 * Endless Game: averted - the game ends when you beat the last of 64 stages. But if you want to keep building your score higher and higher, you can
 * 1-Up: Revealed when you destroy enough mid-sized asteroids in an asteroid field.
 * Warp Zone: the titular Cosmic Gates.

Haggle Man 1 and Haggle Man 2 provide examples of:

 * Affectionate Parody: Of Mega Man to an extent.
 * Adjective Noun Fred: Robot Ninja Haggle Man
 * Damsel in Distress
 * Goomba Stomp: One of two ways to kill enemies in the first two Haggle Man games.
 * Good Bad Translation: Intentional: his original name is Haguruman, which is a pun on the Japanese word for "gear". Extended in the 3rd game, where he can equip Hagglegears, or Geargears.
 * Mercy Invincibility: given to both Haggle Man and HM2's bosses.
 * Multi Mook Melee: each level.
 * Ninja: Robot Ninja Haggle Man is a ninja...
 * Ninja Pirate Zombie Robot: ...and a robot. (He throws gear shuriken!)
 * The Door Slams You: The other way to kill enemies.
 * Smart Bomb: Haggle Man's three companions.

Rally King and Rally King SP provide examples of:

 * Affectionate Parody: The player character is "a guy in overalls and a mustache" (actually a full beard), which Young Arino considers "kind of pathetic".
 * Nitro Boost: In Rally King and Rally King SP, doing drifts can give you boosts.
 * Product Placement: Rally King SP is a joint venture between Rally King's developer, GameFan Magazine, and a ramen noodle company.
 * And also Truth in Television, as special "sponsor editions" of games (such as Archimendes Gradius and All-Night Nippon Super Mario Bros.) were not unheard of back in the Famicom era.
 * Palette Swap: In SP, the palettes for all the tracks past 3 are changed, to be set at night.

Star Prince provides examples of:

 * Combining Mecha: One of the minibosses. Defeat it before it completely links up to get a technical bonus. Since the whole game is a big Shout-Out to Star Soldier, this miniboss is a joke on Lalios, a miniboss from Star Force who behaves in the exact same way and offers the same opportunity for a technical bonus.
 * Deflector Shields
 * Mutually Exclusive Powerups
 * 1-Up: Hidden beneath certain tiles.
 * Reverse Shrapnel: The "Spark Shot", which fires shots in all directions when you absorb three enemy bullets with your barrier. It even makes you invincible for a moment, making it excellent for use as a point-blank weapon.
 * Smart Bomb: Available by, get this, shooting a powerup instead of collecting it.

Guadia Quest provides examples of:

 * Affectionate Parody: Of Dragon Quest.
 * There's a multilayered joke in an item that only someone who's played Dragon Quest will get. In Dragon Quest, the 'warp to town' item is called a Chimera Wing. In Guadia Quest, the equivalent item is called a Naga Wing... and the monsters labeled "Chimeras" look suspiciously like nagas.
 * The layout of the first town is almost identical to Corneria
 * Bag of Sharing: The party as a whole has 63 item slots to share among them, equipped weaponry and your journal included.
 * Beef Gate: If you cross a bridge to another landmass, you can expect to be beat down by disproportionately powerful foes, which serves only as a way to keep you corralled in the area where the game progression wants you to be.
 * Bond Creatures: The Guadias, whom you must defeat in a random battle if you want to earn their services. However, unlike usual Summoned Monsters, Guadias will act automatically after building up their attack for a few rounds.
 * Bonus Boss:.
 * Development Hell: An In-Universe example; the game's original planned release in September 1986 gets delayed all the way to September 1987, possibly lampshading how major RPG releases got delayed back in the day (and still do).
 * Downer Ending:
 * Evil Tower of Ominousness: Celestial Tower, the "reaching infinitely into the sky" type.
 * Everything's Better with Chickens: Seems to be parodied, in that everyone everywhere keeps ducks.
 * Money Spider
 * Monster Allies: Part of the gameplay in Guadia Quest is to make pacts with special "Guadia" monsters, who then pop in during battle to do attacks. Some Guadias are better suited to certain foes, making getting the best Guadia for the job part of the strategy.
 * Shout-Out: A twofer - one of the towns has a duck hanging out in the graveyard, which only says "Aclaf!" when you talk to it - a reference to both the old Aflac Duck and Castlevania II's infamous "graveyard duck" reference.
 * Something Completely Different: The games up to this point have no save function and are basically endless play. Guadia Quest introduces a lot of new mechanics.
 * Stupidity Is the Only Option:
 * With This Herring: The party starts out woefully underequipped despite being sent off to do the king's will.
 * With This Herring: The party starts out woefully underequipped despite being sent off to do the king's will.

Haggle Man 3 provides examples of:

 * Bottomless Pits: Combine these with non-linear levels full of one-way paths to earlier rooms, and screens with a never-ending barrage of enemies just waiting to knock you off whatever platforms you have available, and it's possible to go through the entire game dying only from falling in pits.
 * Darker and Edgier
 * Distaff Counterpart: Haggleman Lady
 * Fighting Your Friend:
 * Genre Shift: Haggle Man 3 looks and plays vastly different than the first two Haggle Man games, resembling something closer to the NES Ninja Gaiden titles.
 * Took a Level In Badass: The title character, able to upgrade himself, use a sword, able to take more than two hits, and overall looks cooler.
 * Powers as Programs: Hagglegears are equipped this way.
 * Public Domain Artifact: The Imperial Regalia of Japan serve as the game's Plot Coupons

Retro Game Challenge in general provides examples of:

 * Author Avatar: Arino appears both as a young boy and a disembodied Kawashima-style head.
 * A Winner Is You: The endings to most of the games.
 * Classic Cheat Code: Each of the games are loaded with cheat codes.
 * Every Ten Thousand Points: Some of the games (such as TOMATO's two shooters) give you extra lives at certain numbers of points.
 * Excuse Plot
 * Future Me Scares Me: Young Arino wonders if he'll actually be like that when he grows up.
 * Getting Crap Past the Radar: Some of the names in the GameFan letters section are a bit racy for an E game, with joke names like "Hugh Jass" and "Mike Rotch".
 * Hey, It's That Voice!: Young Arino: "WHO THE HELL DO YOU THINK I AM?!?!"
 * Intentional Engrish for Funny: "Your adventure is not end!", etc.
 * Star Prince has the especially hilarious "GREAT!" in big flashing letters, followed by "Finaly you saved ancient times ROYAL POWER!" "Thanks for playing - And you will get final bonus!", before counting up the bonus points for however many lives you have left.
 * No Celebrities Were Harmed: The "GameFan Magazine" parody (see Woolseyism on the YMMV page) extends as far as its staff writers, thinly veiled Shout Outs to actual game journalists. For instance, Dan Sock standing in for Dan "Shoe" Hsu, Johnny England for John Davison, "Milkman" for James Mielke, and others.
 * One-Hit-Point Wonder: Cosmic Gate and Star Prince.
 * Pastiche
 * Palette Swap
 * Retraux
 * Scoring Points
 * Shout-Out: The American translation references a few other XSEED-published game characters, including John Garland and Clarissa Arwin as "programmers" of Guadia Quest.
 * Young Arino also compliments your skills by comparing you to the kid in "that game movie where they run away to Los Angeles" that has "The Glove Of Power".
 * Guadia Quest also contains a nod to the so-called "graveyard duck" in Castlevania II Simons Quest, by having an actual duck roam around one of the town's graveyards.

 * That's All Folks: Just wait a minute after RGC's credits.
