So there's no exploit or vulnerability?
9.9 arm11 kernel vulnerability is dead for now?

No, there is no (public) kernel exploit for 9.3+ right now.
Yes, there is a vulnerability ; it is useless (or it seems like it for now at least), but it's still a vulnerability.
Finally, there is no ARM11 (public) kernel exploit at the moment, but it isn't "dead". I'm fairly sure there is one (even an ARM9), we just don't know what it is yet.

If you mean your first post's experiments then no they don't...

Update on 3dbrew.org
The previous version also allowed large negative s32_processorid values(negative processorid values are special values not actual procids), but it appears using values like that won't actually do anything(meaning no crash) besides the thread not running / thread not running for a while(besides triggering a kernelpanic with certain s32_processorid value(s)).
Click to expand...
According to 3dbrew.org, s32_processorid should be larger than -4, which is the code-reversed value of the number of n3ds core.
So I carried out another experiment. It crashed when it took -4 as processorid on n3ds. So it may write the data in the same place as it does when it took 4 as processorid. It's still not clear whether it's exploitable or not.

    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s

  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it

    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying

  • Psionic Roshambo @ Psionic Roshambo:
    Samsung SD format can sometimes fix them too
  • Purple_Heart @ Purple_Heart:
    yes looks like an faulty sd
  • Purple_Heart @ Purple_Heart:
    @Psionic Roshambo i may try that with my dead sd cards

    It's always worth a shot

    @The Real Jdbye, I considered that, but i'll have to wait until i can get the eu version in the mail lol
