for Laramie: i read something on the pk3ds thread that might help you

Use ExInjector to reinject the original decrypted exHeader back into the rom after you build it. Note that you must have extracted the file using CTRTool and not 3DSExplorer.

That's what I was going to say, Plus even so, I know I use CN for my headers, but I used a clean, extracted rom of OR, so It wouldn't have any updates nor tampered headers, ect... New game straight from the game cart.

How do I connect to internet with rundomized rom?

 

[Asia81]

Just inject a valid header, and rename the rom .3dz

thanks for reply.
So when I try to connect to PSS in OmegaRuby,required software update to 1.2.
If it update like this,does the game keeping rundomized data?

If it's for randomized data, it's ok. Randomized data are in romfs, not exefs, so the update erase all exefs content edited.

- What's your native language ?

Thanks.

You guys do know that this is possible to play modified games on a retail cart now using NTR CFW and the layeredFS plugin, right?

I didn't....

That requires the official retail cart though as NTR doesn't patch sig checks and won't work with the Gateway cart anyway. For a lot of us, that's kinda useless. Unless you own a Sky3DS. But I'm not stupid and will never buy one unless the price goes south of $30 or less.

Thank you for the very informative tutorial Asia.
I'm having some problems with the EncryptedExeFs.bin.

Whenever I try decrypting the ExeFS with the "GAME - Décrypter le ExeFS (Partie 1).bat", nothing happens. The command window closes as soon as it appears.

The "GAME - Décrypter le ExeFS (Partie 2).bat" does generate a .bin.out file. I've tried the other methods listed, but when I try extracting it, the window closes as well.
The RomFS works fine and I am able to extract the folder from it.

Would you know what could be the problem? I've trying to figure it out for the past few days.

 

[Asia81]

Have you extracted your "EncryptedExeFS.bin" via 3DSExplorer ? And have you the 7x xorpad in the same folder ?

 

[trakskills]

I wonder why people wanna run this without the update... you can just install the update cia's for those games without entering the e-shop.

Because the update erase some content, like exefs

I have extracted the EncryptedExeFS via 3DSExplorer.
The 7x xorpad? Is that the xorpad extracted from the game? There are a total of six of them if I recall correctly
