Sorry for the delay, when i first downloaded the caesar file there was no exe file for it
and then as far as getting the [NNID music file] for example how do I get it? Do i need a hacked 3DS or do i go somewhere to get that Nintendo Network ID music file? Oh man im confused :/
You need a hacked 3DS to acquire NNID music file.
Also, which caesar version did you download? Because the latest one isn't compiled in exe.
I'll just put out the steps.. assuming you got a hacked 3DS already.
1. Power on the device and hold START to get to GodMode9
2. Go to CTRNAND
3. Press R+A and select "Search for titles"
4. After it's done searching, look for Nintendo Network ID Settings
5. Press A, go to "TMD file options" then go to "mount cxi/nds to drive"
6. Press A again to confirm
7. Go to romfs folder then sound folder
8. Press A at Cave_Account.bcsar
8. Select "copy to gm9/out"
9. Using your preferred method for transferring file, you should find that file in your sd card from gm9 folder.
Assuming you also got caesar..
10. Grab the bcsar file and drop it on the exe file.
11. The file should be extracted automatically, have fun with it.
