(NES) Super Mario Bros. 2 Game Genie Code Requests

[OldSchoolGamer]

I'd like to please request Game Genie codes for (NES) Super Mario Bros. 2

• Luigi jumps/floats like Princess
• Mario jumps/floats like Princess
• Toad jumps/floats like Princess
• Princess jumps like Mario
• Luigi jumps like Mario
• Toad jumps like Mario
• Princess jumps like Luigi
• Mario jumps like Luigi
• Toad jumps like Luigi
• Princess jumps like Toad
• Luigi jumps like Toad
• Mario jumps like Toad

• All Characters instantly pick-up items/objects
  • (There is no wait time/struggle when a character picks up a plant/item/object)
• Can carry enemies through doorways
• Can carry items/objects through doorways
• Always be carrying a plant
  • (Throughout the whole game, your character is constantly carrying a plant above his head. Once you throw it, another plant appears in your hands above your head)
• Automatically catch a spit egg when you get hit/touched by it
  • (This code is useful for the end of level bosses)
• Automatically catch a thrown vegetable when you get hit/touched by it
  • (This code is very useful fighting the final boss Wart)

BeyondTheStatic... I saw the impressive codes that you made recently for the SMB games, so I thought if you are interested, it would be nice to see some of these codes made for SMB2. Or any other codes you come across for SMB2 would be nice too.

Nolberto... I've seen that you have taken a break from NES codes, temporarily I hope. That's why I haven't sent you any requests lately. But if you want to give some of these code requests a try, that would be cool.

And ofcourse, anyone else that would be interested in fulfilling any of these requests or any new codes for SMB2 would be great.

•Luigi jumps/floats like Princess
•Mario jumps/floats like Princess
•Toad jumps/floats like Princess

I think there are codes in the database that enable all characters to float when they jump (unless you're just wanting codes for each individual character).

I'll see what kind of random ones I can come up with. I did manage to find a few recently. I've had other things going on to the point where I haven't been able to hack as much I have been.

Sure, I'll see what I can come up with. This is one of the more fun games to hack

Here are some codes that I have already posted, but felt I needed to tidy up. If a moderator can overwrite the existing codes in the DB with these, I'd most appreciative!

Hard Rock Miner Lv. 1
OLVOTOOK
SUNEGVOG
LXUPPAIT
[B]NOTE: Dig holes into any surface and pull up bombs. The bombs will destroy any part of the landscape. This cheat affects the items you normally get from grass, and some of them may crash the game. Invincibility recommended.
[/B]
Hard Rock Miner Lv. 2
OLVOTOOK
SUNEGVOG
TEUPPAIV
[B]NOTE: Dig holes into any surface and pull up Bob-Ombs. The bob-ombs will destroy any part of the landscape. This cheat affects the items you normally get from grass, and some of them may crash the game. Invincibility highly recommended.
[/B]
Dig Up Mushroom Blocks Anywhere
OLVOTOOK
SXUPAEOU
[B]NOTE: Dig holes into any surface and pull up mushroom blocks. Any grass you manage to uproot will also become mushroom blocks. The surface you pick up will determine the block you drop. For instance, the top of a pot can be carried around and dropped, without losing its properties (you can always go down into it). You can't drop blocks in front of background objects.
[/B]
Icy!
SZEEENGE
[B]NOTE: All surfaces are now slippery.[/B]

[COLOR="#FAEBD7"]
DO NOT USE
Walk Through Walls
SXVEUNSU
[B]NOTE: You can't go through hawkmouths, so disable this cheat to proceed.[/B]
[/COLOR]

And here are some new versions of the Hard Rock codes, designed to avoid potential crashes:

Hard Rock Miner Lv. 1 (improved)
OLVOTOOK
SUNEGVOG
OXUPAEOU
YUUPPAIT
XVUPZAEO
[B]NOTE: Dig holes into any surface and pull up bombs. The bombs will destroy any part of the landscape. Also, all items from uprooted grass will now be bombs. Invincibility recommended.[/B]

Hard Rock Miner Lv. 2 (improved)
OLVOTOOK
SUNEGVOG
OXUPAEOU
PEUPPAIV
XVUPZAEO
[B]NOTE: Dig holes into any surface and pull up Bob-Ombs. The bob-ombs will destroy any part of the landscape. Also, all items from uprooted grass will now be Bob-Ombs. Invincibility highly recommended.[/B]

Now I can work on some of those requests!

[BeyondTheStatic]

Just wanted to remind my fellow hackers about Data Crystal. It looks like it has quite an extensive RAM mapping of SMB2. Here's the link:
Super Mario Bros. 2 RAM map

We might also consider signing up with DC, so we can add our discoveries to their database as we find them

[BeyondTheStatic]

*Can carry enemies through doorways
*Can carry items/objects through doorways

OK, try these out:

Can Carry Enemies & Items Through Doorways
EOXPLPEY
[B]NOTE: You will continue to carry the item to the next screen. Works with anything you can hold.[/B]

Can Climb Vines While Holding Enemies & Items
EPUPIAEI
[B]NOTE: You will continue to carry the item to any new screen you encounter. Works with anything you can hold. Holding an item while on a vine will prevent vertically-scrolling areas to scroll, so drop your item to proceed in those areas.[/B]

These codes were found by looking at Data Crystal's RAM map for this game. The "holding an item" flag ($009C) was used to find the correct addresses in a trace log. I simply circumvented the doorway/vine movement restrictions when carrying items. The programmers didn't want you to do these things, and for a good reason: too many sprites/objects on the screen can slow things down, which makes them look like bad programmers. So they opted to restrict how many enemies/items exist in a particular area by disallowing movement through key portals when carry various things. So you can expect some slowdown when using these cheats

[BeyondTheStatic]

While trying to find a scrolling fix for "Can Climb Vines While Holding Items/Enemies," I found this little gem:

Sky Climber
ELUENLEY
[B]NOTE: Press UP or DOWN to climb invisible vines anywhere. You can pass through ceilings and floors. You can't go through doors in the usual fashion, so just climb out of the screen when centered over/under a door to go to where the doors leads. Climb out of the screen where there is no door, and you might end up anywhere. You will not be able to collect cherries. It is best when used with the "Walk Through Walls" cheat.[/B]

It might be a way to find hidden realms, if any exist for this game. Sometimes when going up or down into unknown areas, you'll be dropped back into a familiar place, yet all the tiles will be changed according to the place you came from. So you might encounter old places with quicksand for walls, and bones for platforms. This game is funny that way :S

[BeyondTheStatic]

some more:

Lift Objects Quickly
EUEEOZEI

Can Enter Locked Doors Without Keys
ELXOZZEY
AYUPGZEI

Birdo Dies In One Hit
AINLXZAL
[B]NOTE: This might affect other bosses as well.[/B]

Enemies Chase You
ENKAKPEL
AINLXZAL
[B]NOTE: It's kind of creepy. Sometimes they will kill each other, and will fly up into the sky when dying. You will need some sort of "jump in midair" or high jump cheat to progress through the game, since some enemies will mindlessly fall to their deaths. Birdo will kill herself quickly. Hasn't been tested with higher bosses.[/B]

Ground Based Enemies Move Quickly
ESXAZGEY
[B]NOTE: Scroll through the level a bit for it to take effect.[/B]

[OldSchoolGamer]

Nice... very nice. I will be testing these as soon as I get a chance.

Unicode... would you care to help me test these?

[BeyondTheStatic]

More codes, submitted for your approval:

All Enemies Die In Your Presence
ESEPXPEY
[B]NOTE: Anything that can die will die near you, even bosses... with the exception of Wart, who only requires one hit before he dies.[/B]

Lifted Enemies/Items Produce Flying Carpets
ENKUOAEI
[B]NOTE: Flying carpets are now available anywhere. If an item can be freely grabbed (i.e. not under the ground), it will produce a magic carpet after it is lifted up. Try to lift enemies/items near *open spaces* to gain direct access to the carpet, otherwise it will be buried too far under the surface to be usable.[/B]

Grass Always Produces Coins
EUSPGPEI

Phanto Is Never Aroused When You're Holding a Key (PRG1 only)
EIXPPLSZ

Birdo Spits Out Small Vegetables (PRG1 only)

[B]NOTE: Doesn't affect all enemies.[/B]

[CRACKdown]

Nice job on these codes so far.

I don't know if it would be possible but a code that you could play the game as the "Sub-world" or whatever they call it when you enter the doors to get potions would be really cool I think.

Also in regards to some of these requests I remember an open sourced program call the SMB2 Discombobulator or something of the sorts that had a lot of good material in the source code, think it used Visual Basic.

[Unicode]

Nice... very nice. I will be testing these as soon as I get a chance.

Unicode... would you care to help me test these?

@OldSchoolGamer: Below is my report for some of the @BeyondTheStatic GameGenie codes in this thread.

Hard Rock Miner Lv. 1
Hard Rock Miner Lv. 2
Hard Rock Miner Lv. 1 (improved)
Hard Rock Miner Lv. 2 (improved)
Dig Up Mushroom Blocks Anywhere
Icy!
Can Carry Enemies & Items Through Doorways
Can Climb Vines While Holding Enemies & Items
Ground Based Enemies Move Quickly
Lifted Enemies/Items Produce Flying Carpets
Grass Always Produces Coins
Lift Objects Quickly
These codes works perfectly on both versions of the game - PRG0 and PRG1.

Slower Enemies x1
Slower Enemies x2
Slower Enemies x3
Slower Enemies x4
These don't work on PRG0, only on PRG1.

Walk Through Walls
This code works on both versions PRG0 and PRG1, but it makes impossible entering into doors too, not entering in hawkmouths only.

Sky Climber
This code also works on both versions, but while it is enabled you cannot collect cherries in the game. It also cause you can get stuck.

I suggest all other codes will be tested by someone having more experience in that game.

[BeyondTheStatic]

Slower Enemies x1
Slower Enemies x2
Slower Enemies x3
Slower Enemies x4
These don't work on PRG0, only on PRG1.

Here are the PRG0 versions:

Slower Enemies x1 (PRG0 only)
XTSPNVZE

Slower Enemies x2 (PRG0 only)
XTSPNVZE
XTSOEVZE

Slower Enemies x3 (PRG0 only)
XTSPNVZE
XTSOEVZE
XTSOOVZE

Slower Enemies x4 (PRG0 only)
XTSPNVZE
XTSOEVZE
XTSOOVZE
XTSOXVZE

Walk Through Walls
This code works on both versions PRG0 and PRG1, but it makes impossible entering into doors too, not entering in hawkmouths only.

This one works much better:

Walk Through Walls
AOXEKYEY
[B]NOTE: Works perfectly with all doors and Hawkmouths.[/B]

Sky Climber
This code also works on both versions, but while it is enabled you cannot collect cherries in the game. It also cause you can get stuck.

Yeah, I'm not sure how to fix the cherries issue, but to get unstuck you can use the WTWs cheat.

Thanks for your time, Unicode!

[BeyondTheStatic]

Here are some more codes.

I've improved the "Dig Up Mushroom Blocks Anywhere" cheat to allow mblocks to be dropped in front of background elements. In the first attached screen shot I'm returning from a block-collecting errand. The block in hand is the missing piece of a wooden platform that I lifted from another place in the level. The second screen shot shows me going down a pipe whose parts I collected and dropped in front of the pyramid. The third image shows the normal behavior of the original cheat. I've penned Birdo into her own little cage >:-D

PRG0 & PRG1:

Dig Up Mushroom Blocks Anywhere (improved)
OLVOTOOK
SXUPAEOU
AYOEKTEP
[B]NOTE: In addition to being able to dig holes into any surface and pull out mushroom blocks, you can now drop them in front of any background structure. The block will embed itself in the background elements above you, thus creating new platforms. You can make lower platforms if you duck while throwing the block. Any block you dig up will retain its original properties, so if you take the top of a pot it will become a pot again after you drop it, and you can still go down into it.[/B]

Quickly Move LEFT/RIGHT While on a Flying Carpet (press B to go faster)
AYKAEGEI
[B]NOTE: You can make it all the way to the last door in 1-2 while flying on the magic rug.[/B]

No Gravity for Enemies and Items
AOEAGIAL
[B]NOTE: This cheat allows you to control the trajectory of thrown items to some degree. It affects enemies as they jump, so when dealing with Birdo you will have to be quick to catch the crystal ball as it travels upward.[/B]

PRG0:

Enemies Chase You (improved)
ESXPAIEY
[B]NOTE: Common land-walking enemies will follow you like a bunch of zombies, thus making the game more difficult, yet still beatable. This is an improvement over the other "Enemies Chase You" code, since it prevents Birdos and Pidgets from getting away.[/B]

Many Enemies Will Hop Around and Chase You (no problems with Pidget and Birdo)
AYOPAIEI

Shyguys Shoot Bullets
ALUOGIEY
[B]NOTE: They will chase and hunt you down. There will be some slowdown in gameplay. [/B]

Shyguys Jump and Shoot Bullets
EYKOAIEI
[B]NOTE: They will follow you and hop like mad. There will be some slowdown in gameplay due to too many bullets existing onscreen at once.[/B]

Enemies Keep Bouncing After Being Dropped
ENXPTIEP
[B]NOTE: Enemies that jump naturally (Tweeters, Snifits, Ninjis) /might/ eventually get back up. Shyguys will never recover. You can pick them back up as they struggle for survival. When a bouncing enemy encounters another enemy, they will both die.[/B]

I'm just about done with this game for now, unless I can improve another code that I found (but never posted).

[OldSchoolGamer]

Your an animal BeyondTheStatic. These are some sick codes that you made, as usual.

Thanks Unicode for testing these codes out. I haven't had time yet to test them. But I look foward to playing this entire game utilizing many of these codes.

Thanks... I hope they work out OK.
