Then what's the point of making a 3ds file? what's even the point of sky3ds??
Allowing you to play (non-modified) .3ds files on <10.4?
sky3ds is to play normal roms and the 3ds file you generate is to be converted to a cia.
Can you help me with that?, my .cia isn't working XD

But if I convert this to cia can I run it on sky3ds? I really have no space on my system memory card..
No, you have to use a cfw

i have a cfw but I have no space on my sd card.. Why is it so difficult to play this .3ds file? Why is the cfw not enough to play it? This very tutorial states the 3ds file will be "playable"

If you don't have space on your SD card, free some up! Remove a game that you haven't played in a long time/didn't enjoy. Or get a bigger SD card and transfer NANDS. Your choice.

Get a bigger sd or try to free up some space, those .3ds roms only work on gateway cards

All I have on there is the cfw stuff and hbl.. It's a 2gb card that came with my ds. This tutorial says the 3ds file will be "playable"

So you're saying if I spend another 70$ on gateway on top of the 95$ sky3ds+ cost me it will then work?

I never told you to buy a gateway... seriously, getting a bigger sd card for your 3ds would be enough/better

So, I'm not asking you to provide me with ROMS but since uploaded roms are essentially dumps of retail cards, can I just download a rom of said game I would like to modify rather than using Braindump? If not, then sure I'll just use Braindump, but circumventing the braindump process seems preferable.

Optional: Turn this .3ds in .cia for CFW

Coolio. My bad for not reading the other methods (as I'm on 9.9). I'm looking to contribute to translations since I've a portfolio and hobby for that kind of thing. Hopefully I can do something with Corpse Party 3DS.

I see, it's because it probably needs to run the game or something, since you're on 9.9 you can downgrade to 9.2, it's pretty safe as long as you make sure you have the right uncorrupted files

I'm not going to risk that, actually. I'm fine with 9.9, and I fully endorse the HANS convention for translations/romhacks. I don't like the older firmware conventions. So long as I am below 10.3 (currently 9.9), I would be fine I would imagine. I have no reason to ever update my firmware either.

I've extracted my romfs/exefs with ctrtool, but I can't find any ExeHeader.bin... any idea why?

edit: I'm stupid, I forgot to dump it haha.....

--------------------- MERGED ---------------------------

We can't use 3DS Builder on Windows Vista ? Cause I can't select the files, only the folder

--------------------- MERGED ---------------------------

Okay now i'm getting "Your selected Exefs is missing something essential"..... My Exefs is normal, unmodified and already decrypted...

My exefs folder only contains exefs.bin (either the one dumped with ctrtool, or the one dumped with your application)
Can I send you the exefs file and you try to open it in 3DS Builder ?
