@DJ Omnimaga wanted me to make this, so I am :P
I have an Everdrive N8 and an NES at home, and I love to play on it often. One thing that's sometimes fun to do, besides playing the games, is making up useful, funny, or just interesting Game Genie codes. I will post new codes I make for new games as I create them.
Also, yes, every code here is of my own creation. Almost.

Thanks for those codes. I haven't gotten any time to try them as I got sidetracked by many other things, online and offline. I'll take a further look later, though. I'm particularly interested by the SMB/SMB3/Tetris ones. Also wtf about the 2-player Tetris mode? Do you mean the game includes an unfinished one?
Yes, Nintendo's Tetris for NES originally was going to include a 2-player mode. It got cut, but most of the code was left in the game, and is functional (but it crashes if anyone tops out). That code enables it. It's most comparable to Battle Mode in later Tetris games, with each player even sending garbage lines to the other player upon clearing lines. It's a shame that it was cut, because it's actually a fun mode!
Funnily enough, there is another code in the official Game Genie manual for Tetris NES giving a 2 player mode (ENEALYNN), but it was that one player controlled the direction the piece moved, and one controlled the orientation.
COINAGE you get 1000 gold
QUERRY you get 1000 stones
I hope noone notices I have never even touched a NES >_>
It's not even querry
it's quarry
tsk
I decided to put my hacking skills to the test, and fix what I've always wanted to fix within Super Mario Bros: making it so Small Mario powers up to Fire Mario when collecting a Fire Flower (because, oddly enough, he doesn't :-\ ). This took 12 Game Genie codes, though, so instead of putting it in the Game Genie list, I'm attaching it here as an IPS patch.
Patch it to an original Super Mario Bros ROM with a utility such as Lunar IPS. This will fix the issue of powerups not powering you up enough.
Also,
@p2, neither of those codes are valid. Yet, oddly, enough,
GGENIE is. :P
@JWinslow23 they were cheats from Age of Empires 1 ;)
also good job on that patch :thumbsup:
Oh, OK then.
And, as it turns out, it's easier to "fix" the powerups in Super Mario Bros 3 (where the same "Small Mario won't power up to the actual powerup" quirk exists for the Super Leaf and the Fire Flower). There are unused flags to see if those powerups are coming out of Big ? Blocks (unused, as in, there are none of those powerups that come out of Big ? Blocks), and if a powerup has come out of one, it powers Mario up to that immediately, regardless of powerup status. "Fixing" that game's powerups, then, comes down to two codes. It's amazing how much unused stuff is in that game.
above my level, but doesn't ths call for a second patch, enabeling most of that unused code to give the game a new touch? ;)
A lot of patches to unlock hidden or unused features in SMB3 already exist. Here are some examples.
- The hidden debug mode can be accessed with the Game Genie code KKKZSPIU, or you can activate it the "intended" way with GGUXSKXV+KZUXNKXV+OGUXVKXV by holding A+B on the title screen with Player 2. (I say "intended" because there exists a check within the code to see if Player 2 is holding A+B at the title screen, and the area of the code that executes when the check is successful is NOP'ed out...but there is just enough space there to enable the debug mode.) A patch to accomplish the same, with a hacked-in menu to show the effects of the debug mode better, is downloadable here (http://bmf.rustedmagick.com/cr/files/smb3dbug.ips).
- There is an unused functionality coded in the game that would toggle Mario being invincible whenever the player presses Select. (A popular guess seems to be that this is a remnant of the debug mode, but I doubt it, since Select changes powerup status in debug mode.) The code is still there and fully functional, but the game unconditionally jumps past it. The Game Genie code LPOGVPYX will enable this functionality.
- There are 15 unused levels still in the game's code that seem to be early versions of final levels, or levels made for testing. In three of these levels, there are some new enemy types, the Green Parabeetle and the Gold Cheep Cheep. One of the levels, a World 6-like ice level, can be accessed with the Game Genie code AOZULT (which simply forces immediate entry in the level tile you're currently standing on), because the START tile contains a pointer to this level. An IPS patch that allows access to all of these levels through a hacked overworld map is downloadable right here (http://themushroomkingdom.net/stuff/smb3ll.ips).
- There are MANY bonus games that went unused, but remnants of their code still exist within the game. A good write-up on what exactly these are and what they're supposed to do (and what they do instead) is available at The Cutting Room Floor (https://tcrf.net/Super_Mario_Bros._3/Unfinished_bonus_games), and a patch to access these bonus games is downloadable right here (http://sonicepoch.com/sm3mix/smb3bonus.zip) (apply to the Japanese ROM).
I remember some of the unused worlds from that hacked world map. Aren't some super glitchy and impossible to finish, though?
Yes, some are incomplete or don't end properly. They are all playable, though.
Bump.
In Super Mario Bros, RAM address
$03F0 keeps track of the number of blocks hit, but no routine actually uses that value. So, I wanted to turn the coin counter into a counter of this variable. Once I realized it's not that simple for the display itself, I did a whole lot of workarounds that basically make hitting blocks the new equivalent of collecting coins, and collecting coins now do nothing. And yes, hitting 100 blocks gives you a 1-UP now.
Here are the Game Genie codes I used, along with what they actually accomplish separately.
| SPASKT+SPYUVL | Coins do nothing |
| AZTAKZ+ULTAVX+VYTASX | Hitting a block increments the coin counter |
| IAZLUG+PLZLSK | Hitting any block gives 50 points (if these codes weren't here, they'd give 200 points) |
| AAPLKT | Actually breaking a block doesn't count for an additional 50 points |
| YGTETY | The coin icon is replaced with a brick icon (because clarity is important) |
Apply every one of these to implement the full functionality, or only do the ones you want.
As well, I've made a jump counter using some other Game Genie codes. See how many jumps
you average in Super Mario Bros!
| SPASKT+SPYUVL | Coins do nothing |
| AEZUPG+AXZLIG+EXZUAG+UUZLYK+VNZLTK | Jumping increments the coin counter |
| ZATETN | The coin icon is replaced with the letter A (for "A button") |
Bump.
Added a lot of new Super Mario Bros codes! Most of these have to do with powerups.
| AAZUZT | Mario can always shoot fireballs, regardless of his powerup |
| AEGLKG | Powerups don't move |
| AYAPKL | Hidden 1-Up blocks are always active (as opposed to only being active after collecting a certain number of coins) |
| AYZIPY | As Fire Mario, press B to kill all enemies on-screen |
| AYZSVA | Instead of becoming Fire Mario when collecting a Fire Flower, you go to the next world after a few seconds |
| AZPIOE | Mushrooms behave like 1-Up Mushrooms |
| ENAISA | Enemies are powerups and powerups are enemies |
| ENZUUK | Mushrooms don't move |
| GAGLIT | Mario can't shoot fireballs underwater (because physics) |
| GIZSVA | Instead of becoming Fire Mario when collecting a Fire Flower, you turn into Small Mario, but he can't hit blocks |
| LAAIKE | Powerups, in addition to their power, also give 1-Ups |
| PEZLEK | Fire Flowers move like Mushrooms |
These codes are very fun to play around with, and
AAZUZT+AYZIPY makes you truly unstoppable!
Also, I made a bunch of codes that reveal some hidden items.
| LZZENK | Hidden 1-UP blocks are revealed! The blocks' location is revealed with a small exclamation point |
| NGZEUK | Hidden coin blocks are revealed! The blocks' location is revealed with a small letter C in a circle |
| OZAANG+OZPEUG | Vines in bricks are revealed! The blocks' location is revealed with a small vine-like shape |
| PZAEUK+PZPENK | Starmen in bricks are revealed! The blocks' location is revealed with a small * icon |
| TZAENK+TZZAUK | Coins in bricks are revealed! The blocks' location is revealed with a small coin icon |
| VGAAUK+VGPANK | Powerups in bricks are revealed! The blocks' location is revealed with a small Mushroom icon |
| VKPAUK | Powerups in ? Blocks are revealed! The blocks' location is revealed with a small Mushroom icon |
All of those codes are really helpful, and you might even discover some hidden items you've never seen before!
Bump.
I was playing through Takeshi no Chousenjou recently, and I couldn't get far, but I wanted to see the ending. Apparently, according to an internet rumor, punching 30,720 times at the title screen warps you to the final room of the game, which sounds outlandish. However, looking through the code of the game, it's entirely true!
Therefore, I had to make a Game Genie code related to this. My results are EGOYESOK and GONNOGLE (both attempts at making "readable" codes), which do the same thing: punch once at the title screen to warp to the final room of the game.
The ending, of course, is underwhelming. :P
Hm, that's interesting. Sounds like something to TAS.
