Uncompiled Source Code & Dev Stuff in N64 ROMs

[shygoo]

For whatever reason, a handful of N64 ROMs have uncompiled source code in them! Here's everything I could find by scanning for C keywords:

File	Size
Chameleon Twist 000F4B6C.c	3,738 B
Fighting Force 64 (Europe) 00356000.c	28,709 B
Fighting Force 64 (Europe) 00361003.c	4,093 B
Fighting Force 64 (Europe) 003BB000.c	8,181 B
NBA Live 2000 (defines) 004E4978.c	22,064 B
NFL Quarterback Club 98 (defines) 003EABF8.c	13,011 B
NHL Breakaway 99 000B35E6.c	23,066 B
NHL Breakaway 99 000D9018.c	28,728 B
NHL Breakaway 99 000F3F60.c	8,215 B
NHL Breakaway 99 000F7000.c	12,168 B
NHL Breakaway 99 001227D2.c	2,094 B
NHL Breakaway 99 00133000.c	19,013 B
NHL Breakaway 99 00153080.c	12,312 B
NHL Breakaway 99 0015C090.c	8,192 B
NHL Breakaway 99 001600A8.c	4,096 B
NHL Breakaway 99 00162F62.c	158 B
Powerpuff Girls Chemical X-Traction (defines) 005DCA30.c	10,400 B
Premier Manager 64 (Europe) 00003844.c	60 B
Shadow Man (Brazil) 0004B230.c	3,536 B
Tom and Jerry Fists of Furry (defines) 00BC4910.c	17,392 B
Wayne Gretsky's 3D Hockey '98 007E1000.c	126,976 B
Yoshi Story (Japan) 000B7568.c	281 B
Yoshi Story (Japan) 000B76C8.c	138 B

(See attached zip at the bottom to download all the files.)

Oddly, almost all of these files are cut off or overlapped by other data. In one instance, there is even a snippit of C code randomly sitting between two compiled assembly routines!



In the Chameleon Twist code, it looks like there may be a bunch of strings in Japanese but I don't know how they're encoded. I tried viewing the file as Shift-JIS and EUC-JP, but neither of those looked right (I wouldn't know for sure though).

There are a few humorous developer comments that can be found in the NHL Breakaway 99 code:

// Kill all children task of the main hockey task. This kills
// a shit load of junk (cameras, ai tasks, track tasks, etc etc etc)

// void Kill_hockey(void)
//
// Kill the whole damm thing.

On a somewhat related note, I found a leftover path to an audio file in Michael Owen's World League Soccer 2000 (Europe) that suggests the developer was frustrated with the Nin-shitfuck Nintendo 64:



And heaps of Windows trash that somehow made its way into Fighting Force 64 (Europe):



I also came across this large SYLK file near the end of the CyberTiger ROM: CyberTiger 00D96DB6.slk
It can be viewed with spreadsheet software like Excel or gnumeric. (Thanks queueRAM for identifying the format!)

Very interesting finds Shygoo.    TCRF would thank you.

[Ehm]

Text encoding in the Chameleon Twist data seems to be Windows Chinese Simplified, CP 936 / GB-2312.

Awesome, thank you!

Here's a scan I did for filenames: http://shygoo.net/n64-uncompiled/n64-filenames.txt -- Not as cool as actual source files themselves, but still interesting to see nonetheless.

Just came across some very fishy assembler directives in Excitebike 64:

file "nes.bin"
resource "NES-excite"

incbin "excite.c1"
incbin "excite.gfx"
incbin "state.cpu"

endresource
endfile

I checked to see if data from the NES rom was present in the N64 rom, unfortunately I didn't have any luck. There is some C code in this ROM too but it's just a bunch of extern int declarations.

Edit: Didn't realise the game had an "Original Excitebike" mode, should've checked that out

I'm willing to bet there is a lot of uncompiled stuff in Glover 2.

As long as you're here mentioning Glover 2, any chance I could get a response in the topic you posted?

There's a Glover 2? I'm finding out about a lot of sequels I never knew existed this year.

I scanned the Glover 2 ROMs for the usual C stuff, but nothing turned up. I was told that source code ends up in ROMs due to some compilers not properly clearing memory, so I'm not sure there would be a difference between prototype ROMs and normal ROMs in that regard. (Btw, those roms are labeled z64 but they're actually n64.)

I also did some more scanning for code that uses the IS Viewer 64's magic number 0x49533634 (ASCII "IS64"). Here are all the ROMs/addresses that have it:

If we're lucky some of these ROMs will still support debug logging without too many hacks. It's already known that the Zelda Master Quest debug ROM still has everything intact: https://www.youtube.com/watch?v=gPMSRGqrjOg
