Getting Roms from the extracted Romfs folder from N64 working in other emulators

Disclaimer: I support in no shape or form any way of Piracy.
Get the Game in a legal way.
I only post this as a form of a tutorial.

1. Homebrew your Nintendo Switch Console via the RCM or Modchip solution
2. Get a subscription to "Nintendo Switch Online + Expansion Pack"
3. Download the Emulator Pack you want to use (in this case the NSO N64 Emulator)
4. Start the application at least one time to generate the keys you need to dump with Lockpick_RCM
5. Dump the keys
6. Now there are two ways to extract the Romfs folder
6.1 You can dump the romfs folder directly with NxDumptool (will take a while since its a lot of files)
6.2 You dump the NSO N64 Emulator as .nsp files and extract the romfs via a Switch emulator (I suggest Ryujinx)

7. Locate your Game inside the romfs/titles folder (e.g. Zelda Majoras Mask would be inside the "N-1407_e" folder)
8. Inside there is a file with the ending .bnz which is actually an archive
8.1 I already tested if this file will work if the prefix get changed to .n64. It does NOT.
9. Now you need to get the "Cave Database Manager" made by @DarkAkuma
10. Once you did set up Cave you use Tools --> .bnz --> Unpack .bnz to unpack the archive
11. It will create a .bin file of the selected archive just renaming this file to the prefix .n64 will make it work with a n64-emulator

Congratulations
You can now play the N64 Games in another emulator.

Even though using this rom is possible it will afaik not be possible to patch a mod on it because the checksum validation will return an invalid checksum.
I don´t know if i did something wrong somewhere that caused this or if Nintendo itself applied some sort of patch that messed with the checksum.

If you are aware of a fix for that feel free to post a response to this thread.

This will get your switch Banned

would chinese ique rom run smoothly?

Dumping your games will not get your console banned.

What step exactly makes you think it could lead to a ban?

@Random_Emulator if you open the bin in a hex editor you can determine the endianess of the ROM.

For example:

Big Endian/.z64:
SUPER MARIO 64

Byte Swapped/.v64:
USEP RAMIR O46

Little Endian/.n64:
EPUSAM R OIR 46

The second you stop paying for your nintendo expansion thing, you then legally have no right to use those roms any any emulator at all. Not only that it is probably in the tos that you are only renting accest to play them on the included software. This is likely just as illegal as any other method of grabbing the roms (outside of dumping them directly yourself).

If purchasing doesn’t imply ownership, piracy doesn’t imply theft.

Will not result in a ban. It’s not 2001. Hacks are sophisticated enough that things will be okay.

Renting isn't purchasing. Thats why when you stop paying, you can't log in and play the games.

Go for it. I give at least 2 months until a ban appears.
Remember if you hack your switch their is a chance, depending on the hack if it's a high or low chance BUT a Chance still exists

 

[18Phoenix]

Yes, congratulations ...
if you're too stupid to find roms and need to use this tuto.
Getting roms this way is not any more legal of course.
And no one needs CaVE to extract bnz files, what a joke.

 

[KiiWii]

Are the ROMs patched though, or is it LUA patching external to the ROM?

I’d be interested check out ROMs that have differences to the original release if true.

Installing an nsp will get you banned. Playing online games with cheats enabled will get you banned. Using CFW will NOT get you banned. SciresM always uses his Switch with Atmosphere online. My OLED is not banned. My original V1 only got banned after I was dumb enough to open tinfoil in CFW mode, which installed it to my home screen. I even played BotW with a hacked save file, and never got a ban before the above happened.

The roms are ALL unchanged !

The roms are ALL unchanged !

Thanks for the confirmation.

Been hacking devices since I was 12, never had a ban. Ever.

It's been years and I am not banned yet. No need to spread FUD with this "2 months" bs.

I understand why you are being cautious, however when helping someone in a technical forum such as this it does no good to speculate without saying that is what you're doing. It's ok to say this is what I believe will happen if you do that, but it's just my subjective opinion. When we say something like that, but say it's an objective fact without really knowing, well that's how misinformation spreads. I'm sure you would agree with that. It sounds like that's what the others have been trying to point out.

But what he said wasn't incorrect. He said there is a chance which is objectively true. If you want to be completely objective, the answer would be we don't know because none of us work for Nintendo so who knows what will happen but given prior experience, this simply isn't the case. Other people are mentioning their subjective experiences but that doesn't preclude people who were banned for doing similar actions.
