Homebrew [Homebrew] Play Coin Setter (Ninjhax/3DSx edition)

[MrCheeze]

So it turns out yesterday's custom theme tool is significant in more ways than one. Beyond editing themes, it proves that Ninjhax actually allows modification of arbitrary 3ds extdata. The most basic application of which is this, a play coin generator!

This is only the beginning, I'd be very interested in seeing what could result from editing an actual game's extdata. Note that this is not the same thing as save data - extra data normally contains content that can be downloaded from the internet, such as the new Streetpass Mii Plaza puzzles.

EDIT: Actually, turns out only "ARCH_EXTDATA" and "ARCH_SHARED_EXTDATA" is possible to access via Ninjhax, not "ARCH_BOSS_EXTDATA". Most spotpass data goes in the latter, and is therefore not accessible.

Nice! I'll be downloading this tool as soon as I have access to my SD Card reader.

One question - are game updates stored in the extdata? e.x: The Super Smash Bros update content.

 

[MajinCubyan]

Hell. Yes.

 

[MarioBrosThe]

OMG IT ACTUALLY WORKS

 

[MarioBrosThe]

Well I just blew through 300 of the coins on the puzzle pieces lmao.

I don't believe so, since updates are treated differently and downloaded as executable content. Although I've heard that the capability exists to have new Smash tips downloaded silently, so that would probably be extdata.

I thought this was just going to be another one of those "Is it possible" threads. Guess I was wrong, this is incredible, so impressed with where the scene is going right now.

Out of curiosity, would it be possible through Ninjhax's userland access to modify the amount of steps taken on the Home Menu's Step Counter? Seeing as modifying the amount of Play Coins is possible? Asking of course for the 4,001 steps a day you need to take for Pokémon's O Powers as there are those rainy days when you can't go out for a walk.

Yay. Fantastic news. Hooray for the 3ds scene

 

[keyra]

But... if im not wrong, playcoin settrer is one of sdk apps (that gateway access with kernel exploit)... so this mean that ninjhax really can acces kernel...?

No.

The current software accesses the NAND Extdata, which doesn't need a kernel exploit. Since Cubic Ninja can accesses the Extdata, so can we.

Ah ok, now clear, thanks. So this mean, exdata, playcoin, theme, dlc and updates? XD

 

[jamieyello]

Neat. I'll be setting my play coins back to 0 now to avoid my puzzle collection losing it's credibility (I worked hard for that crap) Next time I find a game with some bs play coin mechanic I'll be using this.

Looking like ninjhax can almost do everything gateway can except piracy atm.

 

[dronesplitter]

Hell. Yes.

My sentiments exactly.

 

[aos10]

OMG
hell yes
first good news for the new year

thank you very much

BTW , i think you should remove the link
isn't the actual coin sitter is forbidden ?

I looked up PlayCoins on google, and it said that these can be used to download free games from the eshop.. so is this sorta like piracy?

 

[TidusWulf]

Awesome.

Definitely not.
