It's time for another anonymous treasure trove. Someone has, yet again, posted a collection of highly interesting bits of Nintendo history, in the form of source codes, development repositories, and beta/debug builds of Super Nintendo games. This is an addition to the previously uploaded content we've seen earlier this year, which included beta Pokemon designs, the source code for the Nintendo 3DS, Nintendo 64 prototypes, and other files. In this leak, source code for Star Fox and Star Fox 2, Super Mario World, Link's Awakening, Yoshi's Island, F-Zero, potentially Super Mario RPG, A Legend of Zelda: Link to the Past, and more are all available. Some Twitter users have already gotten their hands on the files, uploading footage of these beta versions of games, such as an early build of Yoshi's Island, seen below.

Downloads for these files cannot be provided, though they are making their rounds across the internet, and have not been taken down from their original source yet.

A bunch of Nintendo prototypes are apparently currently being compiled from leaked source code right now as of this post
First up there's this Yoshi's Island proto with different UI graphics, placeholder music from Mario World, and has a prefix of 'Super Mario Bros. 5' pic.twitter.com/Qqock5RZaS

I just came to ask a thing:

I have the other.7z file, and I want to compile the SNES stuff.
So, what software I need to compile it? I see it's all assembly code, but it is obvious that it needs its own SDK, am I right?

 

[WannyTiggah]

I came here to ask if someone has figured out how to decode the attached files in the emails from the NEWS file.

I'm referring to the stuff that starts with xbtoa Begin:

(blacked out stuff just in case)

From what I found they're "binary to ascii" type of attachment but seems it's a super obscure thing that hasn't been used in years.

Try changing your computer's language to Japanese. I haven't looked through that specific email (only the horny one from Star Fox 2).

 

[WannyTiggah]

It doesn't help me much. There must be some tool that converts that BTOA stuff into sromchk.lzh (that's seems to be a popular compression format in Japan but it's supported by 7-zip)

EDIT: seems that those emails were from international users. Some interesting subjects are:
- the aforementioned sromchk.lzh
- SFRG-FO[Ver.00] (SFRG-FO is the German Release of Star Fox)
- 5 Games (no clue about which ones. Mystery!)

In the NEWS_02.tar\.\local\ directory there's Unix executables: atob, btoa, tarmail, tarmail1, untarmail, untarmail1.
But copied those executables to a Linux virtual machine and I get an error when trying to run atob, either with or without a file as a parameter :

Spoiler

 

[MurraySkull]

Wanted to ask: has anyone gotten the May 18 build of Super Mario Kart working? (The one we have seen so far is April 13).

 

[Kyleboy21]

Okay, so I couldn't extract the files in the NEWS_11.tar file because apparently WinRAR thinks the archive is corrupted.

 

[_n3o_]

For those who got the files, can someone tell me more about it ?

Private and public keys for “various arcade manufacturers”

Thanks

Use 7-Zip.

Be aware that you'll be prompted to overwrite files because Unix/Linux is case sensitive for file names while Windows isn't, for example:

Check the different dates. In some cases it's by some minutes and in some by MONTHS.

Yes, exactly. You need to find the decoding tool for the super obscure thing that hasn't been used in years - an alternative to MIME, UUEncode, and BinHex before these things became more standardized. A little googling turns up some likely candidates.

Probably the keys for Nintendo Wii Based Arcade Board that is used for Tatsunoko Vs Capcom : Cross Generation of Heroes as example.

Tried with ESSCode... the decoded files don't work =C

You probably have to set up the encoded file in a very specific way. The easiest means of checking would be to encode a file on your own, look at the encoded file in Notepad, and then set up Nintendo's encoded file in such a way that it matches. I expect it's also probably picky about the line break format.

And of course if it's a multipart encoded file (such things were common back in the day) and the other parts are not in the archive, there's nothing to be done.

I've tried many atob and ascii85 utilities in Windows 10, Windows 98 and Linux. No success =C

Does anyone know how to rebuild the NES/Famicom romset? I'd like to compare it to No-Intro's.

Thanks.

OMG It *almost* works fully.

I used

decode.py -i 1 -k 'nishi\0'

(from within usr01/eng/Mail/inbox) and a 1.tar.Z file is extracted but then 7-zip can't open it =C

EDIT: THE KEY MUST NOT BE BETWEEN 's. It's just for example -k nishi\0
EDIT2: I'm highly curious about how did you figure out the keys for the emails :o

EDIT3:

In one of the emails there's indeed some build of the German version of Star Fox. Now, if someone can analyze to point at the differences (if any) with the retail version...

EDIT4: The parts of the Super Mario RPG ROM that are in the folders inside SFC\ROM\SuperMarioRPG\JP(/US) can be joined with cmd with:

copy /b part1+part2+part3+part4 output.sfc

Aaand... the game seems to be the finished version. Bummer.


EDIT5: From the "5 games" email, we have:
- NHI02 (single file) and NU803 (split): Don't load in bsnes. From the size I'm assuming they're NES games?
- SHX01 (split) : Super High Impact
- SMU00 (split) : Mario is Missing
- STX02 (split): TAZ-MANIA

From the "bubsy and waldo" email it's literally those games. SGW05 is "The Great Waldo Search" and SUY02 (split) is the first Bubsy.

From the "dungeons and dogs" email we have... Wayne's World ?

 

[Jonnysert]

The bizarre arrangement of Bob-omb Battlefield doesn't seem to sync with the video. I guess the prototype has no sound, and BoB was added in post by the video uploader? Strange choice.

 

[Kyleboy21]

I just used 7-Zip and it acts like it doesn't wanna open it as an archive at all.

 

[eyeliner]

EDIT2: I'm highly curious about how did you figure out the keys for the emails :o

Wasn't me, but the encription method is known and not too hard to grasp.
Also, those were not my main point of interest. I'm having my fun with the NES romset. I love that I have the progs and chars and can rebuild the roms.
Too bad no euro set.
I hope there comes a snes one as well.
