I have A9LH installed and am using SysNAND. I heard some people regularly backing up their NAND. What does the NAND Backup save besides getting the 3DS to work having a unique encryption for your SD Card files? Aren't all saves and CIA stored in your SD card?

A nand backup is in case you do something to the point where you brick your 3ds. If you brick you have a back up that you can restore. The only thing is you have to have a hardmod to be able to inject a nand backup into the actual nand of the 3ds. Most people don't hardmod unless they brick, so its always a good Idea to have a backup handy.

You can also restore NAND backups with Decrypt9, but that requires 9.2 or A9LH, of course (and a mostly working system; in the case of A9LH all you need is for A9LH itself to be intact).

The NAND contains your system firmware, and a few config files (e.g. parental control PIN, NNID info, serial number, etc.). Keeping backups of it let you restore it as if nothing ever happened to your 3DS, same as if you backed up a failing hard drive. Most game saves and applications are stored on SD, yes, but others like DSiWare are saved and stored on the actual NAND itself.

Keep regular backups (and copies of those backups in the cloud like Mega or Mediafire, in protected zip files) and you'll go a long way if disaster hits.

I already know that NAND Backups are for to restore in case you brick your 3ds. Thats one of the reasons why I installed a9lh. If i dont use dsiware, regularly backing up NAND is unnecessary right?

  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    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
