My switch came with 4.01, which means 5 fuses burnt. As soon as I got it I took a full NAND backup via Hekate CTaer 3.0. I have never taken it online, always airplane mode.

Since then I have updated the firmware to 5.10, causing the 6th fuse to be burnt, rendering my old NAND backup useless(?).
I have also done a lot of stuff on my switch that will cause a ban as soon as I taken it online.

Looking forward I would love to be able to utilize future proper emuNAND solutions to take my switch online.

My question is: Is there a way to load this old NAND at least temporarily, upgrade it to the latest FW and start over from there? This way I could clean up my traces of homebrew. The bootloader should not allow to boot fw4.2 with 6 fuses burnt, but is there a way around this?

If you boot thru RCM, you'll bypass the fuse check.
So booting to Hekate, restoring the backup and choosing stock will allow you to boot normally.

Right, I see.. So I could restore nand, launch it from RCM and Hekate CTaer, update it.. and hope that these things does not leave any traces.

Maybe im not the only one with this issue and someone comes up with a method for this that makes it safe(r).

Exactly.
Restore -> boot thru RCM -> update

And then I guess it all comes down to how detectable one single RCM boot is for Nintendo. Maybe since I only boot it from RCM with update 4.01 (and not a later version), it may not send any data to Nintendo. I read that later versions include more data.

Apparently, hekate "masks" (or covers up, idk) that you are booting from RCM.
Don't quote me on that.

Well thats fucking great. Thanks for your info, as soon as there is a proper emuNAND out I will do this. I am not convinced to use the SX OS one yet.. I only get one chance for ban :)

I'm guessing after you boot in RCM and restore, you can update via gamecart to 5.1.0, then you would be able to boot normally. Don't quote me on this since I've never touched switch hacking.

    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.

    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

    @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)
