Title: [SOLVED] Where to find the "Baserom_US.z64" for ROM Hacking (OoT/MM)?

Post by HackerNoob64 » Sat Apr 18, 2026 2:15 pm This guide assumes you have legally obtained your baserom

Hey everyone, I’m trying to get into N64 ROM hacking (specifically Ocarina of Time / Majora’s Mask). Every patch or tool I download (like the randomizer or a decompression tool) asks for a "baserom_us.z64" or "baserom.z64" as the source file.

I know I can’t just ask for a direct download link to a copyrighted ROM here (rules are rules), but I need some guidance.

What I’ve tried:

Questions for the pros:

Note for mods: I am not asking for a direct link to copyrighted material, just the technical hash values and legal methods (dumping/archival).

For OoT 1.0 US (the most common baserom): CRC32: 6dba6a1a MD5: 5bd1c1077b0e78ccf5d8e525cef22b45 SHA-1: 688bdd3dbd8c3bd72d1feb56fc48d8dab7f75f6c File size: 32,768 KB (exactly) Byte-perfect filename: Legend of Zelda, The - Ocarina of Time (U) (V1.0).z64

Search the Internet Archive for "Legend of Zelda, The - Ocarina of Time (U) (V1.0).z64" – the top result should be a clean dump. Compare the hash after download. Title: [SOLVED] Where to find the "Baserom_US

For dumping your own cart: Look up the "Sanni Cart Reader" (open source) or a cheap RetroBlaster – both are under $60 if you DIY.

Do not use "baserom.us.z64" from random ROM sites – they often have bad headers or are corrupted.

The file baserom.us.z64 is the required base ROM file for compiling and running the Super Mario 64 PC

port and various mobile versions. It is essential for asset extraction during the build process of projects like sm64pc, sm64ex, and other native ports for devices like Android, Steam Deck, or the RG351.  Key Requirements for Download & Setup 

Exact Naming: The file must be named exactly baserom.us.z64 for the build scripts to recognize it.

Region Specific: It must be the US (NTSC-U) version of the Super Mario 64 ROM. Other versions (EU, JP) require different naming conventions like baserom.jp.z64.

Format: The ROM must be in Big Endian (.z64) format. If you have a .v64 or .n64 file, you may need a web swapper or conversion tool to change its endianness.  Where to Place the File 

Placement depends on your platform and the specific builder you are using: 

Note: I assume you mean "BaseRomusZ64" (a popular modded/baseline ROM build used for Nintendo 64 mods/emulation). If you meant a different project, say so and I’ll adapt.
