C:Multi-Task Code|EE64-54A1|lrdrokol@aol.com|<p>Future Change!</p> <p>This will allow you to talk about stuff that happen and stuff that will happen. Just talk to anyone and turn on the GG!  Or use it in battle it will SCROLL through various messages. Use this to your advantage.</p> <p>FOR EXAMPLE:</p> <p>1. When "Poo" scenario occurs. Turn on the GG and talk to your master. 2. He will talk to you regularly and he will talk to you as if you passed your test. 3. Turn off the "GG" and WALLAH!!!!  You have Poo. to join your party without going through his test.</p> <p>There are lots of places to use this, such as:</p> <p>1. MoonSide - Talk to the guy blocking your way. 2. Tenda Village - Talk to the STRONGEST Tenda.</p> 
C:Multi-Task Code NOTE|N/A|N/A|<p>Swap O' Rama</p> <p>1. Turn off GG. 2. Got to a shop and BUY!!!! 3. Turn on the GG and you will scroll thru out all the shops in the GAME!!! 4.  If you found a particular SHOP turn off GG to buy.</p> <p>Buzz Buzz is back!!!</p> <p>Yes, Buzz Buzz will JOIN your party all you have to do is: 1. Turn on the GG 2. Get out of a room.... 3. Buzz Buzz joins you. 4. Turn off GG.</p> 
C:Level 99 After Battle|EE2E-54A1|lrdrokol@aol.com|This is better than the start up level code because it affects your HP and PP.  You'll get maximum after 1 battle. Works for all characters. 
C:Weird Sound Test|EEB3-CDA4|Strato|<p>Start a new game and you will go to a blank screen with some VERY weird sounds and music playing.</p> <p>NOTE: Do not turn on your Game Genie until your are out of the setup screens.</p> 
C:Sound Test|33B3-CDA4|Strato|Start a new game and when you get to Ness's house, press the left direction.  Ness will start walking and will walk through several scenes of the game while almost all of the music from the game plays.

C:Level Up|552E-54A1|dmbtim@aol.com|Get a bunch of levels after a battle. Make sure the battles aren't instant winners. 
C:Level Up #2|992E-54A1<br>773E-54A1|dmbtim@aol.com|Get a bunch of levels after a battle. Make sure the battles aren't instant winners. This code works basically like the other one except you don't gain as much exp. 
C:Night Vision|EE67-57A1|dmbtim@aol.com|Keep code on at all times. Go to menu and select "Goods". Night Vision is automatically turned on. This code also has some other weird effects. If you talk to any store clerk they will usually skip what they usually say and automatically take you to the option of Buy/Sell. Some  store clerks won't even bother and will ignore you. 
C:Fast Money Code!|EE9A-E5F5|Tony Hedstrom|This code lets you get lots of money. Here's how: Buy a Bread Roll (for $12) with the code turned off.  Then, turn the code on and sell the Bread Roll back for $32,646! 
C:Access Debug Mode (In-Game)|6B84-7D04 <br>3184-7D64 <br>3E84-7DA4|DarkSerge|Did you know there's a debug menu in earthbound and you can only access it thru the Multi-task GG code? You can only access it at three places using the code: inside Dungeon Man, Scaraba Bazaar, and The Place before the final battle.<br><br>For information there's a FAQ about it located here: http://starmen.net/mother2/tips/Debug05.htm <br><br>Of course there's another way to get to it too. .I was searching around the starmen.net forums and found out that someone found a better debug menu with a kirby sprite on it. A guy hacked a code to access it but the only problem is you could only access it when you first started up the game (after you resetted the game on a emulator) and you couldn't use it during the game. (You can find the code for it and a picture here: http://forum.starmen.net/ultimatebb...=8;t=000350;p=1) <br><br>I decided to mess around with it and I found the code you see before you!<br><br>This code above lets you enter the debug mode screen with kirby right after you load a save game.<br><br>When you exit the debug mode screen thru some of the options, you'll still be warped to Tenda Village, but the options aren't pink anymore. You can leave the Village thru the doors now, and you can access the debug options as much as you like now without the game freezing on you.  
C:Walk Thru All|CB93-746F|Mars and LordTech|It lets you walk straight through any texture on the map, including doorways, and you can even walk completely off the map. The only thing you cannot walk through is sprites (people, signs, lampposts, etc.) and enemies (you'll be launched into battle). 
C:Walk Thru Walls|FD93-776F|Xodnizel|It is identical to the above except that if you hit a doorway, cave, or other warping device, you'll successfully warp. The above code acts like they don't exist; this code treats them like normal.  T:Infinite Item Codes
