Hacking Harvest Moon, crashes and possible exploit

[NickMagliaro]

Hey guys,

I have noticed that a lot of consoles are hacked by some sort of crash (e.x. wii had bannerbomb and the ps3 overwrote c++ objects causing crashes) and then the exploit is placed. I have noticed that the game "Harvest Moon: Tail of Two Towns" crashes a lot. Although it may not be a full system crash (I dont know based on what I have seen) it freezes up the game. I also noticed that if you take the game out when it crashes it will ask you to press the home button and, if you do this, the whole system freezes, I assume its a crash. I was wondering if this is any help for an exploit to get 3ds-mode or any sort of exploit that can be placed, I assume through sd card or similar. Just a thought, let me know.....

Next time it crashes, eject the cartridge and see how the 3DS responds.
Link's Awakening DX and Metroid (ambassador title) have 100% reproducable freezes that can be solved by ejecting the SD card.

isnt "sugoi desu ne" well known^^
its the Japanes equivalent to cool / awesome

Crashes don't mean shit. Until you exploit it yourself, then it might have chance depending what function you are able to influence.

Still Japaneese.

I believe the person is making a joke, since that is pretty much a rhythm fever quote >_>

Crashes are one thing but the trick is either causing it and being there with code to run afterwards.

The classic not even pseudocode example would be

Read value (stop when you get to a 00)
In game creation only allows for 10 characters- developer assumes all is good.
A hacker comes along and edits the save where the value is stored to many more characters which can be exploit code by itself (if the game just carries on writing it will hopefully hit the game code at which point you have hopefully overwritten the code with your own or a jump to exploit code using similar logic).

There are many variations on this* but that is the general idea. A game might just crash because it encountered a wrong value or was just badly coded and did something before it should have (probably the usual one I see- it is known as a race condition and Harvest Moon has a long history of this sort of thing).

*edit forgot about the autoparse of youtube on the new version

not my usual example video but it popped up and is pretty good/probably a better example than my usual one)

Equally there are many things Nintendo could have done to prevent this from being bad for them (see the likes of the 360 security) but I am now starting to shoot things down without trying anything which is probably bad form.

like i said, it was just a thought. thanks for the input thought.....if there was a way some code executed on the crash that would be awesome, but i guess no dice seeing as i am not a good programer.

We have a thread for this sort of thing for a reason, we don't give no kind of shit about anyone's "AMAZING HACK IDEA!!' that won't work, or probably won't work. See here next time you have an "idea" http://gbatemp.net/topic/307018-awesome-3ds-hacking-theories/

if you have a idea about hack 3DS, please see http://gbatemp.net/topic/307018-awesome-3ds-hacking-theories/ first and please replay on them and not create new one, is make harder to find you idea
