The title screen and main menu of the Nordic release of the Nintendo DS port has a few notable differences from the European version. Specifically, the "Licensed by Nintendo" screen uses the company logo instead of just plain text, a logo for Mobiclip Video Codec present in the European version is removed entirely, and a language select screen with options for Swedish, Danish, and Nordic translations is included.

Beating the game with 100% completion unlocks a final cutscene which reveals that the monkey who gave you chants throughout the game is Spoiler:AiAi from the future. This cutscene further reveals that Spoiler:AiAi and GonGon invent the magic energy balls that the series' cast run around in, Baby is AiAi's future son, and that MeeMee is Baby's mother.

When the game was initially released in Japan, it was only available to people who bought a copy of the November 1996 cover-date issue of Japanese magazine CoroCoro Comic and filled out a mail-order form for the game. This promotion lasted from the day the issue was released on October 15 until December 27, 1996. As a result, on some official Japanese Nintendo and Pokémon websites, October 15, 1996 is listed as Pokémon Blue Version's first release date in Japan before it received a wider retail release there on October 10, 1999.

The title "Untitled Goose Game" was first used after submitting the game to Fantastic Arcade, a game festival in Austin, Texas, due to the team's indecisiveness with choosing a name. The game was internally referred to as "Goose Game" before then, although that was deemed unusable for the final release. However, the placeholder title they chose stuck due to positive public reactions, technically (and ironically) leaving the game without a title.

One Piece: Great Pirate Colosseum and Dragon Ball Z: Extreme Butoden, two games developed by Arc System Works for the 3DS, both received an update in November 2016 that added cross play where characters from one game can fight characters from the other game.

According to Cave Story creator Pixel around the release of Cave Story's Secret Santa in December 2021, the Mimiga named Santa did not get his name because it was related to Christmas or Santa Claus, but because he was the third Mimiga that Pixel designed during the original game's development. The name actually comes from "san" ("三"), the Japanese numeral kanji for three. At the same time however, Pixel acknowledged that some segments in the Bushlands where Quote has to travel through and collect items from fireplaces (including the one in Santa's house) may have subconsciously made him think about Santa Claus, though he did not realize this at the time. Santa would later take on a Santa Claus-like role in Cave Story's Secret Santa.

Darth Vader and Yoda from the Star Wars series appear as guest characters in the game, with Darth Vader being exclusive to the PlayStation 3 version, and Yoda being exclusive to the Xbox 360 version. According to Bandai Namco Entertainment America's then-senior business development director Zack Karlsson, this was a deliberate choice to match the color schemes of the respective consoles, with Darth Vader’s shiny black armor matching the PS3's look, and Yoda's green skin and white robe matching the 360's look.

In a 2004 interview with the magazine Nintendo Dream, designer Yoshio Sakamoto revealed that developing Wrecking Crew permanently increased the storage capacity of Famicom games. The cartridges previously had a maximum storage of 128 kilobytes (kb) of uncompressed data for programming and 64 kb of data for images and sprites in the game itself. Wrecking Crew's gameplay pushed developers towards a 256 kb capacity while still having 64 kb of image data, allowing for more complicated ideas to be explored. This increase would not be seen again until the Famicom Disk System allowed for 1 megabyte (1024 kilobytes) of storage per game.

In a 2006 interview with Dengeki Online, lead writer Kinoko Nasu and character designer Takashi Takeuchi noted that they were never fully satisfied with the original PC release of Fate Stay/Night, considering it only 95% complete. However, rather than their beliefs stemming from the inability to add content, the pair stated that their main issue was that they didn't remove enough, with Takauchi calling the PC version cluttered and overlong. Consequently, a major challenge during the development of the PlayStation 2 port, Fate/Stay Night: Réalta Nua, was striking an ideal balance between streamlining the game and adding in additional material to incentivize purchasing it over the PC version.

According to a series of tweets on TeamKill Media's Twitter account, they announced the game would remain exclusive to PlayStation 5 and would not receive PC or Xbox Series X/S ports despite being requested by players. The reasons why were in regard to a lack of staff to handle porting it to Xbox consoles, and personal concerns over the chances of mods of vulgar or sexualized versions of the game's characters being added in the PC version. They stated that they held their voice cast in high regard alongside their artistic vision for the game and story, believing that mods would tarnish that standard and giving players the option to mod was "not worth the extra money we can make." This announcement led to complaints from some accusing TeamKill of both moral grandstanding and being paid by Sony to keep the game a PS5 exclusive, the latter of which they denied and insisted they received "no investment or support from anyone but ourselves." One of the most notable complaints came from Postal series developer Running With Scissors, who put out a statement defending modders and their role in buying games and keeping their fan communities alive with free add-ons.

In the English-language version of Super Mario 64 DS, a Toad holding a secret Power Star gives a hint that the mirror room contains an "ally with info", referring to how one can pick up an invisible Power Flower to access a Wario painting in the reflection of a Luigi painting. This hint has perplexed many players as to the identity of the "ally with info", with the leading theories being either that the Power Flower is the ally or Wario is the ally. The original Japanese-language text doesn't exactly give a concrete answer, with the Toad simply saying that he saw an invisible person inside the mirror, which is also a mysterious statement, but a contextually appropriate one as opposed to interfering with the hint. However, the European localizations show the real intent behind the English version through extra information not provided in English, that the ally will give a hint by not being reflected, meaning that the ally's identity is actually Luigi. The English version not only left out this crucial context, but also failed to disable the line after Wario is unlocked, something that was managed in other versions of the game.

Although the Wii port of the game was primarily developed with the Wii Remote and Nunchuk combo in mind, the game has limited Classic Controller support via the left and right analog stick.

In the Pet Pavilion, the player can find a pet shop ran by two men named Tennant Wastelander and Lowe Springfield. Also in the area is the West Ende Girls Snack Shop, ran by Dusty Shadowcloud and Jackie Whisperflame. The names and occupations of these characters reference the English synthpop duo Pet Shop Boys, consisting of Neil Tennant and Chris Lowe. The group's 1984 debut single, "West End Girls", serves as the snack shop's namesake. Dusty Shadowcloud's first name and Lowe Springfield's last name reference English soul singer Dusty Springfield, who appeared as a guest vocalist on Pet Shop Boys' 1987 single "What Have I Done to Deserve This?"

The Stone Stomper uses two interchangeable names in-game. In the intro cutscene for Carnival Chaos and during the boss fight in Showdown with Omegaton, the name Stone Smasher is used. However, in both the game's manual and the tutorial for the move Stone Stomp in Carnival Chaos, the name Stone Stomper is used.

A video game based on the 2000 film "Titan A.E." was in development by Blitz Games and set for release in Fall 2000 following the film's summer release. The game had been in development since March 1999 after the company was approached to make it in January: back then, the film was still under the title "Planet Ice". A playable demo was shown at the E3 2000 trade event, only for it to be announced in July that development had been halted. While Blitz Game's co-founder Philip Oliver and a spokesperson from publisher Fox Interactive both confirmed that the film's poor box office performance was partly to blame (the film had grossed just over $22 million on a budget of $75-90 million at the time), they also stated that it was "only one of many different factors" that resulted in the game's cancellation.

The 2008 re-release of the 2000 bootleg Famicom game Street Dance contains graphics that depict Jar Jar Binks from the Star Wars franchise wearing an urban vest outfit. Jar Jar Binks' graphics do not appear to have been rotoscoped from any particular scene in his source material as he is not heavily associated with dancing in the Star Wars series, but there was a robotic dancing toy of him released in 1999. However, the Jar Jar Binks in Street Dance does a kicking dance, whereas the toy only does a rudimentary shuffle dance. While there is another dancer that vaguely resembles the dancing title character from the 2004 film Napoleon Dynamite, this is not a case of plagiarism as the character is present in the original 2000 release of Street Dance, which predates the film by four years.

If the Hex values for Zephyr and the tornado are swapped in the game's data, the in-game camera will automatically resort to a first-person perspective by positioning itself within the near center of the tornado. This is because the camera is tied directly to both Zephyr and the tornado.

A Spanish localization for The Legend of Zelda: Ocarina of Time was planned by Nintendo of Europe's Madrid branch, only to be scrapped partway through due to production difficulties faced by the main development team in Japan. Consequently, the Spanish release of the game used the English-language ROM, bundling the cartridge with a 150-page booklet containing all of the game's text in both English and Spanish. The cumbersome nature of the guide and the potential risk of encountering spoilers while flipping through it was considered enough of an issue that Spanish advertisements for The Legend of Zelda: Majora's Mask heavily emphasized the inclusion of a proper localization. Despite this, the guide's Spanish-language text was not added back in for the Virtual Console re-releases of Ocarina of Time.

In the original release of the Resurrection of Evil expansion pack, in a lounge area found in Level 4: Erebus Control, you can play a minigame on an arcade cabinet called "Hellanoid", a clone of the 1986 Taito game Arkanoid. A broken Hellanoid cabinet can also be found earlier in the level. There are only five layouts for each of the game's levels and they repeat in a loop with a gradually faster ball. Notably, two of the layouts are arranged into unique pictures. The picture in Level 4 is that of an Imp's face, while the picture in Level 3 is a depiction of a widely-circulated shock image hosted on the website "goatse.cx" showing a hunched-over male pornographic model stretching his anus open. In Doom 3: BFG Edition and all releases of the game since, Hellanoid was replaced with Super Turbo Turkey 3, a minigame featured in the base game.
