  • Do any of the following have debug modes? This follows from my (andlabs') observation that early Now Production games (at least on the NES and Genesis) all have debug functionality left in:
  • Athena has minor regional differences and possible unused graphics.
  • Armadillo has a special game mode (called "Stone Armadillo" mode, which apparently slightly adjusts physics, palettes, and other things) that can only be accessed when used with the rare "Famicom Battle Box" accessory. The extra menus that can be accessed with the accessory installed should also probably be mentioned on the wiki, as well.
  • Mississippi Satsujin Jiken has leftover text from the Commodore 64 version.
  • Hello Kitty no Ohanabatake - unused demo recorder/player containing recorded demos for Levels 0, 3, and 12, which are totally incompatible with the final versions of the levels (or the level numbers themselves were changed).
  • Jangou a lot of code duplicate from early revision, including graphics. Check if there is something different.
  • Radac Tailor-Made - The ROM in the NES ROM archives included in the 2020-07-24 leak doesn't match what is on the cart (or at least doesn't match the dump of unknown origin that can be found on the web)
  • Roger Clemens' MVP Baseball - The ROM in the NES ROM archives included in the 2020-07-24 leak doesn't match what is on the cart.
  • Star Force has some regional differences, the US version upgraded everything, including harder difficulty.


Game Boy (Color)


  • Dragon Ball Z: Legendary Super Warriors has unused graphics.
  • A prototype ROM of the unreleased game Infinity has been released online, along with the source code, by developer Affinix.
  • Maru's Mission has many regional differences, mostly graphical.
  • R-Type has a sort-of hidden dev credits in the attract mode and a special symbol that one of the developers put in "a lot of [his] earlier Spectrum games". See this interview.
  • Woody Woodpecker Racing has regional differences. The Nintendo logo goes unused in the Japanese and European versions, and all of the Japanese characters from the name selection screen go unused in the American and European versions.


  • Harry Potter 3 has graphics for a...clown?
  • Pokemon Jade crashes after the first level, leaving almost the entire game unused. There might be leftovers from Sonic Adventure 7.
  • Pokemon: Mewtwo Strikes Back:
    • Possible beta material that Makon Soft/Yong Yong would have probably left in with (although, this may not have much possible purpose in with the Li Cheng ROM, with them possibly taking out (unused) stuff, keeping from their programming fix to work).
    • Intro differences between DMG and CGB/GBC. In the DMG intro, Makon Soft/Yong Yong (probably) stole several frames of the intro from Pocket Monster (SNES), however, in the GBC intro, like every Pokémon game of theirs except Pokémon Adventure, they use pictures from the anime. YouTube user XanverKun posted a video of the Li Cheng cart about the DMG intro. It's probably assumed that even probably the original Makon Soft / Yong Yong version has this too, with the intro. However, no proof. But most likely, it probably does, since Li Cheng barely probably would remove anything from the ROM, in their revision ROMs. I, Chowdit1, will probably remake the video in better quality.
    • As a side note, Li Cheng translated the game's name (in Chinese Simplified), as "Digimon (Digital Baby) {Taiwanese name for Digimon} [Shu-Ma Bao-Bei]: Mewtwo (Super (or 'Surpassable') Mew Mew) [Chao Meng-Meng] Strikes Back [Fanji Zhan]. So, it's exceptionally correct except for the series name.
  • Shui Hu Shen Shou has menu icons leftover from Pokemon Gold and Silver.
  • Terrifying 9.11 apparently includes an unused Metal Slug logo (the game is a 9/11-themed port of the Neo Geo Metal Slug).
  • Thunder Blast Man has a few sprites left over from Rocman X Gold.

  • There are several unlicensed SNES games with interesting anti-piracy features.

Nintendo 64

  • The 64DD Mario Artist games have debug features, or at least debug leftovers.
  • There's partial source code for a Mortal Kombat game in the 2020-07-25 Nintendo leak.
  • All-Star Baseball '99 has debug text and a bunch of bin/data file paths scattered in the ROM, but mostly near the beginning, as well as a file/reference to CODE.BIN. (I'm not 100% sure if the latter part would qualify for the wiki but I thought I'd note it anyway.)
  • Killer Instinct Gold has three USA revisions. Check for any revisional differences.
  • WCW vs. nWo: World Tour was later released in Japan as Virtual Pro Wrestling 64 and has differences from its American counterpart.

Game Boy Advance




(New) 3DS

Wii U

  • A way to disable sleep mode is on the external hard drive.
  • Miiverse had debug features. The way to access them may have been removed by updating the HTML or by a system update. But there are leftovers (scroll to post #79) of some sort. Not sure if this should go on "Wii U" page or "Miiverse (Wii U)" page.
  • Rayman Legends' eShop demo from December 2012, and its later Challenges App from June 2013 have some differences from the final game. There are also many notable differences seen in prerelease footage worth covering, most prominently in E3 2012 coverage.
  • GBA Virtual Console Games have code leftover from other projects and Adobe Photoshop. (source: ajd4096)
  • Some games have internal names (source: Random Talking Bush)
  • To be discussed: updates for download-only games.
  • Jeopardy! and Wheel of Fortune very likely have a plethora of unused images and such for the online gameplay features they trumpeted in promos and even on the boxes but never actually delivered. Also, given that these were THQ's last games before filing for bankruptcy a few days later (probably why they suggested the consumer pay $20 more for inferior products), they might have some other unused stuff that may overlap with those of the Xbox 360 and PS3 versions.
  • NES Remix and its sequel have Famicom-related regional differences and unused graphics. And the emulations are likely to have differences as Virtual Console games do.

Nintendo Switch

  • A Dark Room has an outdated ruby-interpreter than can be brought up by plugging in a USB keyboard and pressing the tilde key. It was added as an "Easter egg" by the developer and the game was later taken down. (initial discovery: @yourcompanionAI)
  • Duck Game seemingly contains Windows exes and dlls.
  • Kirby and the Forgotten Land - Unused Yellow Kirby texture?
  • The Legend of Zelda: Link's Awakening has unused level names.
  • Mario Kart Live: Home Circuit has lots of debug strings.
  • Pokémon Mystery Dungeon: Rescue Team DX has lots of leftover assets from the previous two 3DS games (Gates To Infinity and Super Mystery Dungeon). With many animations for story Pokémon from those games leftover in their low-poly model .ab directories, portraits, sounds, and likely some leftover text. It also has some leftovers from the demo version, various unused assets, and cutscenes that were made by developers during development.
  • Pokkén Tournament DX
    • There are four Trainer Titles (all in Extra 1) that are listed as requiring a Special Code to unlock, but only one of said codes has ever been released.
    • The Extra 2 section of Titles primarily (if not exclusively) contains ones awarded for playing in official tournaments. No official tournaments have been held since October 2018, rendering these unobtainable.
    • Revisional differences.
  • Popeye has a lot of unused assets, ranging from textures of human beings to models of various objects.
  • Puyo Puyo Tetris has a debug menu of sorts, though it's barely there. The exact key combo was later discovered: "right stick pressed down + X + B"
  • The World Ends With You: Final Remix has an unused song. It is a different version of the Final Remix version of Make or Break, but the file name (re_B04E_R.ogg) suggests it was at one point a Final Remix of Twister Remix instead.
