Hey folks,

I searched a while for a way to successfully downgrade from 7.0.1 to 6.2
because i just ordered sx pro before i checked if its working (damn dat commercials)

First time i tried i flashed from 7.0.1 to 6.2 directly - ERROR 2000
second time i flashed from 7.0.1 to 7.0 to 6.2 - ERROR 2000
Third time i flashed from 7.0.1 to 7.0 with option factory reset and then from 7.0 to 6.2 with factory reset - IT JUST WORKS!

So now you can create your emunand with sxos and restore the main nand with your backup and your good to go!

Videos and guide I followed and can suggest:

If you have questions ask me im not a pro but i will tri my best to assist you.

You are supposed to do a factory reset, whenever you're downgrading between major versions.
So this is pretty normal behavior.

I did this exact process a week ago. I also missed the fact that a factory reset was needed after a fw downgrade. I'm sure the info is on gbatemp, but I found the tip on a YouTube comment. I ran the whole process using the sx pro dongle. A week later and I'm still screaming at Tetis 99, with the emunand available for sx payloads.

Don't you need the latest firmware for online, tho?

And SX OS doesn't support 7.0.1?? Hahahaha! lol Atmosphere 0.8.4 came out a little over two weeks ago. It's open source. They forgot to copy-paste the code? Lol, TX are probably still in the Bahamas on vacation from all the money they collected.

There's a little issue with factory reset. It changes your pairing key.

So, when you restore your sysnand you can't get paired your Bluetooth devices in emunand AND sysnand at same time.

Yeah I didn't realize this until after the fact. I've just been reconnecting it. I assume there's no other way to have it constantly sync up unless I create another Emunand?

I did the downgrade from 7.0.0. to 6.2.0. without factory reset and everything worked perfectly. Why is it strongly advised?
I still did not power off the switch since I downgraded and now I'm planning to create EmuNAND 6.2.0. and then restore my NAND backup from before the downgrade to avoid any more fuses getting burned.

    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
  • 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

    @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)
