GG Codes for Super Mario Bros. (minus Duck Hunt) - NES

[BigBossman]

Codes added.

What's neat about the walk on background code is that when you jump & hit a cloud it acts as if its a brick. On stage 1-3 you can't pass through the lower parts of the ledges either.

I'm wondering it it would be possible to change the bricks to coin blocks, multi-coin blocks, or hidden power-up blocks / 1-up blocks.

[OldSchoolGamer]

Did anyone have any luck with the Game Genie code:

"Mario's Fireballs Can Break Bricks"

[BeyondTheStatic]

Your new "Walk On All Background Elements (fixed)" code works properly. I don't got any issues with hitting normal bricks and coin ? blocks or walking on them with it enabled. Thanks your for the fixed version.

Other "Background Elements Slightly Rearranged" code also works properly.

Cool, glad to hear it

I sorry if I affect you with my reports for your codes.

No problem at all; I honestly don't mind. I was just slapping myself for not testing my own codes properly. It's always nice to find out if my codes work correctly or not, and having a dedicated gamer such as yourself test them actually makes my job a lot easier, so don't stop reporting! I just wish to focus my attention to other games now

So keep those bug reports coming, Unicode!

Your fixed "Kicked Shells Move Slowly (fixed)" and your new "Outside Backgrounds Are Present In Underground Places" ALOPPGEY codes works great!

But I now found a bugs on most of your new "Landscape Modification" codes.

With "Walk On Clouds" APEPTSEA code, if you go to Heaven Bonus and leave it, you'll get stuck when returning back on main stage because you can't control Mario in any way after he falls from Heaven Bonus, as on screen also there is no timer (I show the problem in the attached screenshot).

Yeah, any time the player enters the screen from above and there are blocks in the way, his maneuvering ability is frozen. It's because the original programmers didn't want you to have control until you fell a certain distance. For now, try the "Background Elements Slightly Rearranged" cheat (below), which should help. If I find another workaround, Ill post it, but I'm just about done with this game for the time being.

Your "On All Background Elements" ESNPPGEL code reproduce the same problem as "Walk On Clouds" code + more bugs:

• you can't hit bricks (except Multi-coin bricks and the bricks with a hidden power-up inside) or step onto them in outside levels;
• you can't hit ? blocks which contains coins or step onto them;
• you can't go down in bonus pipes;
• you can't step on clouds in Heaven Bonus.

Yep, I hastily posted that code (you live, you learn). The new cheats resolve all those issues.

Your "All Backgrounds Replaced With Water" and "All Backgrounds Replaced With Castle Walls" GameGenie codes also have a bug - they won't let you see the Piranha Plants when they are out of pipes (these codes make them invisible). In this way, when Mario / Liugi steps onto a pipe, you may see that you get hurt by nothing while you are actually touched by an invisible Piranha Plant that is come out from the pipe (as your "All Backgrounds Replaced With Water" or "All Backgrounds Replaced With Castle Walls" code made the Piranha Plants invisible).

The programmers didn't need to shift the Piranha Plants to the foreground once they were outside their pipes. To fix that code would cause them to always appear outside their pipes, even if they are "inside" them. Another solution would probably require too many codes. I'm going to move on to another game now

Those two bugs should be completely resolved now, although the number of codes you must enter is greater. For some reason, jumping to a free location and rewriting a section of code fixes these sorts of problems. If a more experienced hacker could elucidate the reasons for why this should be, I would be most appreciative

I have found a workaround for the "Stand On Clouds" cheat. It keeps the water from being drawn for 2-2 and similar levels. It's the only thing I could find that would work! See the notes below.

Fireballs Fly Straight #2 (better than the other cheat)

In this way, when Mario / Liugi steps onto top on a pipe, you may get hurt (when big or Fire Mario / Luigi) or die (when small Mario / Luigi) by nothing when actually you are touched by an invisible Piranha Plant that is come out from the pipe which your "All Backgrounds Replaced With Water" or "All Backgrounds Replaced With Castle Walls" code made it invisible.

I would like you fix these issues.

Requests:

Mario's Fireball Image Modifier (Make it look like Bowser's fireball, or an enemy... can you imagine launching 2 goombas, turtles, Bowsers, etc... instead of fireball sprites?)
Hit Anywhere (Head Collision. Break all destructible blocks on screen in one jump.)

[BeyondTheStatic]

I would like to please request this Game Genie code:

"Fireballs Can Break Bricks"

Yeah, me too. I have already tried, in fact.

Nolberto! I need your help! So far this is what I have found:

Breaks bricks with fireballs #1: Fireball destruction event is rerouted to head/block breaking event.
E1D4=D7 CMP B5
E1D5=DC CMP E1
NOTE: The best fireball block-breaking cheat. Your character will jump up and slide to the right. Block breaking events will occur over your head when the fireball breaks a block.

Breaks bricks with fireballs #2: Fireball destruction event is rerouted to body/coin collecting event.
E1D4=AC CMP B5 +
E1D5=DD CMP E1
NOTE: Seemed like the perfect code... until I noticed random things happening to the landscape after the fireball/block event.

Those codes aren't meant to be added to the database, because they are riddled with bugs.

#1 seems like the best bet. I think all that needs to be done is to find out how to displace the head/block event to match up with the fireball hitbox.

[BeyondTheStatic]

Your "Very Low-Bouncing Fireballs" GG code is nice!

TY.

But your "Kicked Shells Move Slowly" GameGenie code not work properly because I found a few bugs:

• pulley platforms like these in world 3-3 and 4-3 don't work correctly when this code is enabled;

I couldn't find that bug, though I tried with the two main SMB versions. Try the new code all by itself, to see if it adversely affects the game in any way.

• when you stomp a Koopa Paratroopa while it jumping on ground, it will fly out of screen very quickly and you won't be able to defeat it;
• in end World of 3-3 I also got a a graphic errors in the background castle after the flagpole.

[/CODE]

Those two bugs should be completely resolved now, although the number of codes you must enter is greater.

I forgot to mention that my "All Enemies Are..." cheats were derived from a code made my born2party of the acmlm boards. His code changed the first enemy of level 1-1 to a single Hammer Brother, and could be tweaked to change other (single) enemies. A couple addresses up is where I found out how to change all enemies.

small Mario / Luigi can break bricks

I believe I saw that code in the database. Double check that. I could be wrong though and saw it for SMB3 instead.

I like that request of "Fireballs can kill Bullet Bill." I'd like to see that code get made.

[Unicode]

I have a few more suggestions for GG codes for this classic game:

• small Mario / Luigi can break bricks;
• fireballs thrown by Fire Mario / Luigi can kill Podoboo appearing in castle levels;
• fireballs thrown by Fire Mario / Luigi can kill Bullet Bill;
• fireballs thrown by Fire Mario / Luigi can kill Buzzy Beetle.
