** The original ''VideoGame/SuperMarioBros3'' had a debug mode in the form of the Game Genie Code KKKZSPIU. t. Pressing select allows you to cycle through all of the plumber's various forms at will. Press either face button and Select for the Kuribo's Shoe, though it's usually just a [[GoodBadBugs jumble of pixels]]. It also grants you one of every item and a level warp ability. In addition, the power cycle could be twisted into the ultimate GameBreaker by turning into a statue as Tanooki Mario, and cycling before the statue time limit ran out, giving you permanent statue status in any form OTHER THAN Tanooki. Due to a programming oversight, ''Videogame/SuperMarioAllStars'' may give you access to this at random when you turn on the console. ''All-Stars'' itself has its own separate debug mode that can be accessed with various cheat codes.

** The original ''VideoGame/SuperMarioBros3'' had a debug mode in the form of the Game Genie Code KKKZSPIU, which has the power cycle and Kuribo's Shoe effect described above, as well as granting you one of every item and a level warp ability.

** A few cartridges of ''Videogame/SuperMarioAllStars'' left the factory with a debug mode intact. Pressing select in a game of ''Super Mario Bros 3'' in these carts allows you to cycle through all of the plumber's various forms at will. Press Y and select for the [[http://www.mariowiki.com/Goomba%27s_Shoe Kuribo's Shoe]], though it's usually just a [[GoodBadBugs jumble of pixels]].

** ''VideoGame/Mother3'' has a debug menu that's somewhat notable for the fact that, unlike most examples on this page, it's in the form of a [[NotHyperbole literal]] [[https://tcrf.net/Mother_3#Debug_Room debug room.]] This plain beige and white room features a variety of [=NPCs=] from throughout the game that, when talked to, can provide various options such as choosing which part of which chapter to start at, configuring the player's party and level, viewing pre-battle screen transitions, and filling the player's inventory with nuts. The player can also fight the Firefly mid-boss, with this room being the only place where they can see its DummiedOut back sprite in action; losing to the Firefly or choosing a chapter/event to play is the only direct method of exiting this room.

* ''VideoGame/ElseHeartbreak'' has a debug room hidden in Sebastian's house at the very beginning. It's accessible via matrix travel from a computer in the backroom of the first hotel, and contains multiple useful objects and doorways to other test rooms. Unlike a typical debug room, it doesn't contain exploits, but once you understand the game's in-character programming language enough to fully access it you can probably already create any exploit you want.

* The Flash version of ''Videogame/Bejeweled'' has a debug mode that can be activated where you may press different keys on the keyboard for different effects, like change a jewel to a different one, skip levels, and so on.

** The first ''VideoGame/SonicTheHedgehog'', ''VideoGame/SonicTheHedgehog2'', and both parts of ''VideoGame/Sonic3AndKnuckles'' all have debug modes which can be accessed by the player. In Sonic 2, it's done simply by playing the right sequence of sounds in the SoundTest (spelling out the game's release date, one digit at a time, in year-month-day order.) The debug mode in each lets Sonic turn into a variety of items (moved around with the d-pad), and place them onto the level. In ''Sonic 3'', you could also use the item-turning feature to reach Knuckles' paths as Sonic and vice-versa.

** ''[[VideoGame/SonicTheHedgehog1 Sonic the Hedeghog 1]]'', ''[[VideoGame/SonicTheHedgehog2 2]]'', ''[[VideoGame/Sonic3AndKnuckles 3 and Knuckles]]'' all have debug modes which can be accessed by the player. In Sonic 2, it's done simply by playing the right sequence of sounds in the SoundTest (spelling out the game's release date, one digit at a time, in year-month-day order.) The debug mode in each lets Sonic turn into a variety of items (moved around with the d-pad), and place them onto the level. In ''Sonic 3'', you could also use the item-turning feature to reach Knuckles' paths as Sonic and vice-versa.

** ''VideoGame/SonicTheHedgehog 1, 2, 3 and Knuckles'' all have debug modes which can be accessed by the player.

* The Flash version of ''VideoGame/BejeweledTwist'' has a debug mode that can be activated where you may press different keys on the keyboard for different effects, like change a jewel to a different one, skip levels, and so on.

* ''Videogame/Castlevania3DraculasCurse'', contained in the game is a hidden level select where you may choose a stage, which part of the stage and which screen of the stage, as well as the character that you start with (or none). Interestingly, you can choose any value between 00 and FF and invalid stages (above 0E) can be selected. This will commonly result in crashes, but there are also glitch levels as well. Commonly you'll fall to your death, it's recommended to switch to Alucard and transform in order to explore the stage. Also, if you enter a level this way, the first 100 points you get will give you an extra life.

* The Object Testing Arena added to ''VideoGame/DwarfFortress'' is a DebugRoom that's accessible right from the in-game menu, to be used for debugging {{Game Mod}}s.

* ''VideoGame/EarthBound'' has a fairly elaborate debug menu. This menu contains, among other things, a Videogame/{{Kirby}} sprite from ''Kirby's Dream Course'' as the menu cursor - an artifact left by a HAL Laboratory programmer, perhaps, considering how ''[=EarthBound=]'' and ''Dream Course'' were developed at around the same time. Although another more well-known debug menu exists as well - one intended to be used during the game, similar to ''Super Mario RPG''. This menu is also reachable via one of the options from the former... and is significantly trickier to figure out, since it remains untranslated from Japanese despite the lack of a Japanese font. Only a few words are recognizable as compressed, [[GratuitousEnglish garbled]] English - "SUND" for Sound, "TRP-T" for Teleport, and "[=GtZStTI=]" for Goods Edit, for example.

** A few cartridges of ''[[Videogame/SuperMarioBros Super Mario All-Stars]]'' left the factory with a debug mode intact.

Press Y and select for the [[http://www.mariowiki.com/Goomba%27s_Shoe Kuribo's Shoe]], though it's usually just a [[GoodBadBugs jumble of pixels]].

* It's possible to access Debug Island in the second game in ''VideoGame/ShadowHearts'' series with one of the two known patch codes (either after the intro cutscenes or by entering a location on the World Map immediately after entering the screen, without moving the cursor). After gaining access to it player can enter a huge menu in Japanese with lots of subsections and options. It's extremely easy to crash the game though (and the [[BonusDungeon Sea of Woods]] area seems to be wiped from the game, even though it's still listed in the warp menu and you can unlock some of the other [[LimitedSpecialCollectorsUltimateEdition Director's Cut]] features).

* The debug room in ''VideoGame/UltimaVII: The Black Gate'', which contains a cache of plot-relevant items and teleports to plot-relevant locations in the game world, can be accessed by a player who uses a large number of crates to make a staircase, climb up onto the ceiling of a certain building in Trinsic, the starting town, and crawl down the chimney.
** Its sequel, ''Serpent Isle'', had a similar debug room, containing every item in the game once again, but the ''really'' fun devroom featured a lot of posters and statues of Dallas Cowboys cheerleaders, as well as various nude dancers.
