Mario.txt version 1.2: A Catalog of all Available Game Genie Codes for the Super Mario Brothers Series--compiled by Adam Blake This file is not being maintained. You are free to use this file on your web page, but tell me about it via email as a courtesy. Version History: Version 1.0: Original version. Version 1.2: Update completed 12/29/97. All copies lost until one paper copy was discovered 6/30/99, from which this is typed. Version 1.2: 7/10/99 2:12 am. Finished retyping version 1.2. Email me at firstname.lastname@example.org Game Genie codes for Super Mario Brothers 1-2-3 I created most of the music codes for Mario 1 and almost all of the codes for Mario 2 and 3. Credit is given where known, but this is hearsay and as such it is not terribly accurate. However, thanks to email@example.com, firstname.lastname@example.org, and Nintendo Power for compiling many of the Mario 1 codes which were featured on tsr's NES archive in the FAQs section, in a file titled Super Mario Bros-The Stupid File. Some Mario 1 codes come from the SMB Game Genie Page on NES WORLD. A few of the Mario 2 and 3 codes come from: NESJournal #3, NESJournal #5, and Jesse Smith's game page. Disclaimer: These codes were all tested on my CARTRIDGE of the Mario games. They will not necessarily work in an emulator. The music codes will probably not work at all on an emulator, since NESTICLE does not do a very good job of emulating NES sound.

Graphics Scramblers The set of these codes is a subset of the set of Graphics Codes which basically do the same things as each other. They replace certain sprites with others. For example, the left corner of a piranha plant pipe may be replaced with a section of undulating waves. As a result, descriptions are hard to make for each one. I have asterisked or otherwise indicated my favorites, but try them all out and give them your own descriptions. GAEOXG-A wacky graphics scrambler. *AALLLL-A great graphics scrambler. Mario also appears to be underground. PIGPSK-An uninteresting g.s. *ZIGPSK-A great g.s. *ZAGPSK-A great g.s. *ZZGPSK-A great g.s. *OGAOKK-A fantastic g.s., similar to the OSTENA family of Mario 1. OAKOKK-Nothing but corners. SGAOOK PGPOSK OAKOSK-Removes stripes of graphics. *PGAOSK-One of the best. SGSOSK-Mostly blankness. SGOOSK *SGAOSK PGAOOK TIKOKK-Mostly corners.

PIGPEG-Replaces most of the background with bars of color. The OKK family of graphics scramblers is analogous to the OSTENA family in Mario 1. The following are all the codes I have tested, and a formula for generating similar scrambler codes follows the list of codes. KGAOKK XGAOKK LGAOKK UGAOKK GGAOKK IGAOKK SGAOKK VGAOKK YGAOKK NGAOKK PAAOKK AAAOKK APAOKK AZAOKK ALAOKK AIAOKK ATAOKK AYAOKK EAAOKK EPAOKK EZAOKK ELAOKK EIAOKK ETAOKK EYAOKK PAAOKK PPAOKK PZAOKK PIAOKK PTAOKK OAAOKK OPAOKK OIAOKK ZAAOKK ZPAOKK ZZAOKK ZLAOKK ZIAOKK ZYAOKK XAAOKK XPAOKK Formula for generating similar graphics scramblers: 1st letter can be any letter 2nd letter can be A, P, Z, L, G, I, T, or Y 3rd letter should be A 4rth letter should be O 5th letter should be K 6th letter should be K or G Music Codes Even if you are not interested, try these out anyway. These are the codes I spent the most time and energy compiling, and I love them like children :) Anyway, give them a try. EPZXVL-This code will freeze the game and leave the music playing. Great for listening to codes below work without the hindrance of a time limit. ALSUZI-Another eternal music code. TVLLLL-Another eternal music code. PUUUOT-Another eternal music code. OOOVYU-This is the archetypal music code for Mario 3. The first level music is nothing special, but 2 on is simply incredible! It is almost the same every time you run the code...the resultant music is so complex you will think it is intentional! I have never heard a NES utter these kinds of sounds before. OOOVYN-Map music sounds like melody has a hard time keeping up with drums, level music effects are same as EEEVYN. OOOVYI-Melody of map music sustained longer, sounds like a pure sine wave, and melody of level sustained as well. OOOVYS-Similar to OOOVYI. KKKVYU-The music is normal except for the bass part, which is very odd. EKKVYU-Similar to KKKVYU, with small differences. PEKVYU-Also similar to KKKVYU. TOKVYU-same story. TTTVYU-On the map screen, a music "sampler" will play which goes through first small cuts (time up, hurry up, finish level) music and then goes once through each map's music. Next is the finishing game music. Music box music follows, with strange noises accompanying it, and it eventually degenerates into wonderful strange noises. Check this out! EEEVYU-A sampler within a level, running through all normal level music, and going into a beautiful fast noisy rave-up! EEEVYN-Map music is just bass and drums, certain notes in level are sustained longer. EEEVLU-Like EEEVYU but starts with swimming music. AALVYU-Slows down all map and level music except for certain levels, like 1-1 and 1-5, which sound fantastic. Let me know if you find other great-sounding levels. AALVYN-Affects map and levels, makes drum samples trigger so fast they become strange grinding and humming noises. ANLVYU-Freezes upon entering a level, but makes odd crashing noise over and over again. Sounds like you are being chased by the mechanical Hitler in Wolfenstein 3d. YYYVYU-Music periodically stops, then starts again. NNNVYU-Freezes the game and makes a wonderful grinding noise. NNNVYS-The harmony part on the map screen is sustained. Freezes when you try to enter a level. XUNXUN-Affects drum part on map music. This also makes your timer just the ones digit, occaisonally with arcane symbols replacing the other digits. Level music is normal. YUYXUN-Affects map music slightly, and adds another level 2 to map. YXYXUN-Like YXYXUN with different sound inserted. YEYXUN-Like YXYXYN with different sound. YOYXUN-same idea. VYYXUN-One part of map music gets out of time with rest. OYLXUN-One part of map melody slows down. OYYXUN-Similar to OYLXUN. In addition, game freezes seconds after entering a level, making it another ideal "infinite music code". EPOXUN-After passing first pipe in 1-1, game freezes but occaisonal drum sample is triggered. After an indefinite time interval, only the drum part resumes at full speed, but with strange touches you will NOT hear in the game normally. YYLXUN-First level map music is FANTASTIC! YYYXUN-Different first level map music. OPOXUN-The aforementioned graphic code also affects the music. When you trigger a sound effect like getting a mushroom or being shrunk, the game appears to freeze. Wait, however, and you will see that the effect is slowed down greatly, with pleasing audio results. AOLUZI-Makes music "skip" occaisonally. AESUZI-Adds tom sample to melody, also interferes with graphics. VVLLLL-Makes wonderful noise for about one second, then freezes :( I need a code which will do this without stopping the music! VVLLLI-Level melody off-time, Mario bounces when he walks. KVLLLL-Freezes game and makes different noises. EEOXUN, EOOXUN, EXOXUN-These freeze like EPOXUN, but resume the drum track instantly. EPOXUN+VVLLLL-An interesting combination. AOLUZI-The music is altered and skips. NAXULT-There are lags between different sections of the music, and it occaisonally changes slightly. AOZXEL-Occaisonally when this freezes, the drums will resume as in EEOXUN. POVXXL-Infinite music code. OXTVYZ-A wonderful code which switches some of the drum samples around. OXTVYT, OXTVYV-Either of these codes make some wonderfully dissonant map music. OXTVYI, OXTVYS-Either of these codes take the harmony, bass, and half the melody out of the map and level music. OXTVIT, OXTVIV-Either of these codes change the sample for the hihat. OXTVYP-Makes incredible map music, and adds extra hihat to the levels. OXTVGT-Changes the drum samples on the map and in the levels. OXTVYN-A nice-sounding and cool-looking freeze. OXTVPZ-Different fantastic dissonant map music. OXTVGZ-Changes the samples of some of the drums. OXTVGN-Changes the music of the entire game so that only one note is played in rhythm over and over. Really fun at first, but you can only take so much. OXTVPT-Incredible code! Map music level 1 is fantastic. Extra hi-hat, beeping, notes added. Level music similarly affected. Sometimes there are no drums in the level music at all. Try this out! OXTVZT-Like OXTVPT, but no extra notes are added. OXTVYT-Like OXTVPT, but no extra hi-hat is added. OXYVPT-In the map and level there is no hi-hat. OXAVPT or OXEVPT-In the map and levels the bass is playing very oddly. OXPVPT-On the map and in the levels the bass is almost not present. OXLVPT-No bass in map, levels. OXKVPT or OXGVPT-On the map, there is no hi-hat, and an extra snare of some kind is being played out of rhythm. In the levels, there is a crash on every beat being played with some weird samples. Nice code. XLYXUN-Certain parts in map music malfunction. XXYXUN-Hihat in level music goes crazy! XXXXUU-Yet another infinite music code. ESSVYN-Fantastic dissonant funky map music! One of the best codes. EASVYN-Only bass and drums on map, sustains certain parts longer in level. EEEVYN-Same as EASVYN, but different things are sustained. ESZVYN-The sound effect of Mario jumping is different. *ESSVAN-Fantastic code. On the map, an all-drum all-star rave-up with sparse bass playing octaves, but freezes in the level. ESSVLN-Fantastic. Demented music. All pitches replaced. Sounds random in some sections, but it is the same each time. Sounds really cool underground (as in 1-5.) ESSVTN-Similar to ESSVYN, but slightly different. Listen to the beginning of level 1 map music! ESAVAN-Doubles certain instruments, adds sustain, makes music in map "fuller." Also adds stuff similarly to level music. ESPVAN or ESOVAN-Minor changes in the map-sustains the last note of each phrase. Also does the same in levels. ESTVAN or ESVVAN-Kind of like a combination between ESSVYN and ESSVLN which does not freeze when you enter a level, but works its magic there as well! EAAVAN-Snare and other non-hi-hat samples are off. VTPVAN-Affects both map and level music. Takes out some drums, adds more kick, and adds weird static to the music. TTTVAN-Small alterations to map music, but level music is fantastic, similar to ESAVAN with major differences. YYYVAN-Like ESAVAN but with an even fuller sound. NUYVAN-The hi-hat stops playing on the map. XXLXUU-Music odd when you die. Also a graphics code. Also a behavioral code. ESSXUU-Music odd when you die. Also a graphics code. Also a behavioral code. SSSXUU-Music odd when you die. Also a graphics code. Also a behavioral code. PTVUYS-Music at the beginning of 1-1 is warped. POXPOA-Level one is frozen with music music of the Spade House playing. POZTTS-Great map music, freezes in level and makes "modem noises". POPTTS-No melody. POLTTS-1 note played rapidly over music. Freezes in level. POSTTS, POITTS-Like POLTTS but affect level also. ESSTTS-1 part playing oddly. EPOVLU-No snare drum. KKKVLU-Bass odd. POTTTS-Death music odd. EAEVLU-Odd sample triggers. EEPVLU-Like EEEVYU but different order of music. EEKVLU-Bass is odd. EEIVLU-Freeze with crashing noise. EEKVLY-Every note of the music is shifted down an octave. EPTTTV-No bass. KSTTTT-Drums odd. ESTTTZ-Samples switched. ESTTZZ-Samples switched.

OZTXVY, XZTXVY, UZTXVY-Parts of map staggered. SZTXVY-Double melody. TVTVYZ-Samples switched. ESTVZY, EETVZY-Great dissonant map music! KKTZZO-Kinda like VVLLLL. Freezes almost instantly. KKTZAO-Intro like KKTZZO, then resumes normal music. Also a graphics code. KKTZGO-Great musical intro to level. KKTZZA, KKTZZE-No harmony, half the melody is gone, great sound effects and warped music. This strange music reminds me of the elevator "music" from Metroid, and since it sounds like nothing else in the game and recurs in other codes, I will refer to it as metroid music. KKTZYA-Map music odd, metroid music in level. KKTZYE-Strange freakout music. AKTZGA-Map sfx odd, metroid music in level. KKTZLE-Map sfx odd, metroid music in level. Freezes.
