Hacking DSiWare Downgrade with almost ANY DSiWare Game!

[srwgin]

old guide inject usa version sudoku into your eur dsiware
no matter which dsigame you bought it not work after transfer
new guide inject eur version into your eur dsiware
after transfer it will work
but you must buy game meet specific size requirements

+ EUR DSiWare
+ Uses exidiahax (temporarily)
+ `.app` size of >= 9,628,672 bytes
+ `public.sav` size of >= 113,908 bytes

if you do not know which game should buy
just wait report like Strongal said

In that video you can see how he downgraded Firm0 to 10.4 and then went to 9.2 on an EU 3ds using Jagged ^^

Get the game .app from freeshop. Extract it out with FBI.
Then get the hax save from: https://github.com/yellows8/3ds_dsiwarehax_installer/releases

Going to try this tonight with my JPN 3ds. If i remember correctly the LOE save was universal across regions

The only issue is exidia JPN has been pulled for years and it's MIA on the scene.

Things look pretty bleak for JPN dsiware downgrades.

Its not in freEshop?

No, it's not unfortunately. Amazingly, I checked last night and there's only 30 dsi games total on the JPN titlekey site.

Yeah I saw that, it makes my last point pretty null considering i had the information already

Btw, I've figured out the JPN 4swords offsets so we can port it now.
Below are the only changes necessary. Honestly, I would just compile it enough to get all.dat and paste it to 0x1400 in the public EU or US public.sav files. That's what I did. It's kind of a pain to compile fully on windows.

https://github.com/yellows8/dsi/blob/master/exploits/4swordshax/4swordshax.s
#define HEAPCTX_ADR 0x2177170
#define TARGET_FUNCPTR 0x20C9118+0x24

Only thing that stinks is it appears the save has to be 16KB or the game erases it. There are a lot of games with 16Kb saves at least.

I bought it because who cares about 2€ and that could open up my next console but I can't get it to work. Getting the same problem as @Txustra

Hello, I bought SUDOKU to try this, I applied both the patch to the app and the savedata, but when I boot the game, my 3ds turns off....

What is it?? Does anyone know??

I can confirm jagged Alliance working.

Never mind, I already fixed this using Troubleshooting from Plailect's 3ds.guide !

I own Four Swords and an o3DS (11.0 US) With Menuhax, should I just wait for Slowhax now? I'd just like to confirm so I don't end up missing out on everything. I hear a lot of people discussing injecting exidiahax and such, what are these for, necessary? Sorry & Thank you ~ w ~

@InTheBeef also staying on 11.0, won't work if you upgrade to 11.2 (you probably already know this but just in case).
