I carry my 3DS around my college campus, and have racked up a TON of coins... I could care less about the 10 play coins/day limit, but I was mostly bummed when I realized I couldn't have more than 300 play coins overall. This cap feels very arbitrary, and attempts to figure out how to remove it have resulted in... literally nothing. There is nothing out there that explains how to, or even why you can't remove the 300 cap.

So I'm asking this for what seems like the first time in the history of the Internet: is there a way to remove this 300 max play coin cap? I'm not looking for ways to manually set my play coin count to above 300; I'd like to be able to walk around and have it passively continue giving me play coins every day.
 
Dang, I'd be interested in this as well.
I get why the cap was put, so you can't just endlessly grind the coins to do some crazy stuff in games but at the same time...... ehh??
If I'm walkin' around with my 2DS I should be able to gather as many as I can. 'Specially with it bein' only 10 a day.
 
Edit: Nevermind, ignore all previous instructions:

https://3dbrew.org/wiki/Extdata#Shared_Extdata_0xf000000b_gamecoin.dat

The above date stores the last time new Play Coin(s) were obtained. The contents of this file is updated by home-menu. PTM:GetTotalStepCount is not checked constantly, after home-menu boot this is only checked when waking from sleep-mode. Each time home-menu updates the contents of this file, home-menu will set the Play Coin total to 300 if it's higher than the 300 Play Coin limit.

Home Menu loads this file / opens this archive during startup. When accessing this file fails, like when the file/archive is corrupted(or at least on older system-versions), the result is a brick due to Home Menu using svcBreak. Yellows8 bricked a 3DS this way due to corruption via invalid FSFile:Write flush flags. When opening this extdata archive(0xf000000b) fails, Home Menu executes svcBreak.

Here is your answer, it's too big of a pain in the ass to fix all the checks and would often result in userland brick.

There is also this little workaround:

iamevn

Homebrew  Thread '[Release] For Anyone Who Walks A Lot'

Currently a little ugly but this is in good enough condition to release.
The idea is that if you walked a lot in a day and have reached the 10 play coin per day limit, you can just run this little program and it will make up the difference for you.

Download here: https://github.com/iamevn/for-anyone-who-walks-a-lot/releases/tag/v0.1b
To install, just extract the folder in the zip file ('for-anyone-who-walks-a-lot/') into the /3ds/ folder on your SD card. You do need the cache.bin file that's in there so don't...

Shoot, really?? Is there any way for me to create a backup so I can tinker with it? This 3DS has become a pet project of mine, and I wouldn't mind using it to learn some new skills. I have no idea how to edit stuff like this, but I'm willing to figure it out.
 
I was also interested whether it would be possible to change how the play coins are awarded?
Normally, it awards 1 coin per 100 steps with a maximum of 10 coins per day. But I think it would make much more sense for 1 coin to be awarded per 1000 steps, with 10000 steps as the ultimate daily goal to get the maximum of 10 coins in a day.
1000 steps are very easy to reach with just a short walk, while 10000+ steps is something you only get on days with a lot of walking.
That kind of awarding system would feel much better to me.

I'm sure there is but restoring it would be a different matter once you've bricked it. Probably need a custom payload/NTR to be able to restore it from soft brick. You're also looking at modifying a bunch of things at firmware level so... probably going to be beyond your skills (not to be rude).

So you're saying there's a chance...

Not rude at all! I'm a junior in college, I highly doubt I have the skills (yet) to do something like that. But, if it's at all possible, maybe I'll figure it out eventually. I have a surprising amount of time on my hands right now.

My interpretation of the 3dbrew stuff (correct me if I'm wrong) is that you would want to take a look at the Home Menu and do some reverse engineering to figure out what functions interact with playcoins and then hopefully it would just be a matter of figuring out which one modifies the amount of them. That function might have a hard-coded value of 300 or something like that, that you could modify with a .ips code patch for the home screen. I'm far from an expert on all this, but it theoretically wouldn't be too hard. The hardest part would be parsing the home menu code in the first place. I might look into this more over the summer, I've been interested in doing some work with the 3DS home menu.

Would you like to get in contact with each other to collaborate on this over the summer? I was thinking about doing the same thing; perhaps we could tackle it together.
 
Hi all, I've created the first fully functional Play Coin uncapper!
  • Removes 10 a day limit
  • Removes 300 total limit (now 30000)
  • Works despite games trying to reset the count
  • No need to boot a HB app, works by hooking code to the home menu directly
Demo:

Will be making a formal release soon, but let me know if you wanna test it out!
 
  • Wow

That share link is nonfunctional, and says the viewer doesn't have permission to see the file :)

ah oops, should be visible now

Thanks! When you make a release, can you share any material related to making this mod? I'd love to look at it. Also, there might be a small argument against allowing the cap to be above triple digits, as there are other home menu mods that move the playcoin counter and may have it aligned in a wierd way if the number of playcoins exceeds 999.

Will that be configurable in any way? If I were to install this, I would prefer to still keep the limit of 10 coins a day in place. Or even to change the rules on how they are awarded (see my previous post).

even if it isn't, I might make my own modifications to it and see what's up. Also might look at the 3ds home menu more in depth over the summer cause work is less of a concern then

Streetpass games take forever to complete even with uncapped limits (i still havent) so im surprised you'd want 1 every 1000 steps, I suppose its doable to implement that though as a config screen
