Requirements:
- I have rxTools emuNand 10.7 with sysNand 9.2; I think you need to have CFW ready.
- Downgraded 3DS Browser (If you don't have one, follow this tutorial to get the downgraded 3ds browser: https://www.reddit.com/r/3dshacks/comments/402cri/how_to_downgrade_3ds_browser_to_more_vulnerable/)
- Exchange Booth Available (If you don't have access to Exchange Booth, download Mii Plaza Games cia and then you will have the access to it. Don't ask me for the link; google it.)
- 9999 ARCode Tickets: 127FD9F6 0000270F (For O3DS USA Only; "It doesn't work for N3DS at all. You'll need to use either a gateway or NTR to use any codes for N3DS users.")

Steps:
1. You first need to have downgraded 3DS browser, or else, you will not be able to do this.
2. If you have downgraded 3DS browser or are ready, go to https://lunarcookies.github.io/cheat.html to generate QR Code.
* For O3DS USA, use the above code and put that code into the "input codes" to generate QR Code.)
3. After getting QR Code, press L+R and then scan the QR Code.
4. Launch the browser and then wait for it to close with error.
5. Profit.

* If it is not working, open Mii Plaza first!
* UPDATE: It seems like Mii Plaza resets after you close it and open it back up.
If that happens, repeat the step, or use this code for "permanent tickets."

O3DS USA:
99 Plaza Tickets
0176CF90 00000063
027FD9F6 00000063

Questions? Leave a reply; I will try to answer.

You can if you have N3DS!
I only have O3DS so this is the method for those people who don't have N3DS.

I have an n3ds... what can I do with this baby??? ("baby" as in, the n3ds console, don't read that the wrong way...)

 

[Vanth88]

There are tons of EU, N3DS codes out there!
Search for them! >

It doesn't work for n3ds at all. You'll need to use either a gateway or NTR to use any codes for N3DS users.

Thank you for the info!

You should check out the thread on N3DS Mii Plaza NTR plugin.
It should be there!

I'd much rather cheat at the Streetpass Mii Plaza games instead, I'm literally missing just 3 more tickets from the fishing game and the RNG for getting specific rods is worse than finding shiny Pokemon. Are there any ways to cheat the fishing game? I've been wondering for a long time now.

 

[MartyDreamy]

No chance for Old EUR?

 

[keyra]

finally!!!
gotta wait for EU version

 

[chronoss]

I'm waiting for EU O3DS

Have this from a little while ago - EU AR codes for O3DS, Mii plaza codes



Paste the following codes where it says "input codes"

1000 fantastics
027FFFA6 000003E8
02846B12 000003E8

max streetpass hits(999 999)(like anyone would ever get that many hits the normal way!)
027E8940 000F423F
02845BFC 000F423F

mii plaza tickets (60)
01789B78 0000003C
027FFE36 0000003C


You can change to the exact values that you wish by changing the numbers in the second part of each code string. The first part is the location, the second is the value in hex. To convert decimal to hex use an online converter such as this http://www.binaryhexconverter.com/de...-hex-converter
Put the value you want in the left box and it will show you the hex value in the right box. The second string needs to be 8 characters long. The end is the hex value and that is preceeded by zeroes.
e.g 20 is 14 in hex so the second string would be 00000014.
50 000 is c350 so the second string would be 0000c350.
You must change the second string to the same thing for each location as in the examples above.

Anyways, input the codes in the box and click generate QR.

Go into mii plaza.
Press home (do not close) and then the left and right shoulder buttons to activate the camera.
Press the QR button on screen to activate the QR reader.
Scan the QR code that you previously generated to open the browser.
The cheat code will then run and crash the browser. no matter. Just resume the suspended mii Plaza to benefit from the cheats.

Note that some values are dynamic, meaning that even though the code has run, you need to change the value in game as well, e.g. to see the new plaza ticket count, you may need to use a ticket or gain one and to see the max number of hits, you may need to actually get another hit.

It is not possible to set the number of miis in the plaza because each mii would need to have data created for hair etc; it's not just a matter of a number for that so it must be done the old fashioned way.

Edit old/original 3DS only, since New cannot run the browser exploit.

I copied the following cheats from a thread on here that I cannot now find. I haven't checked these as I've finished the games, but might be useful. Thanks to the original poster.

Do you have codes for O3DS? That will improve this thread a lot!

They are all O3DS. AR codes won't work on N3DS

 

[putti]

Oh I meant USA! Forgot to put US after O3DS. XD

Thanks for sharing what you have, unfortunately I've already maxed out my gold in the game across all the hours I've dumped into this game so I definitely dont need that one. Anything in regards to the fish themselves, Logbook, or even rods? I'll take literally anything else but the gold.

 

[Ikki Barri]

Oh I meant USA! Forgot to put US after O3DS. XD

Sorry, no. I don't have a US 3DS to work it out.

I don't have anything, I'm afraid, because I finished all the games before I knew about AR codes. You might be better off with an edited save, anyway. If any number you want to change depends on anything else (like the number of miis in the plaza depends on having the data for each separate mii), then it won't work without some clever programming that I'm just not capable of doing. AR codes are only useful for changing quantities of things that don't have any other conditions.

Ohh nice, so if I wanted a duplicate rod of one I already own you can do that? or no.
