CRC 3322EFFC identifies the original Japanese v1.0 The Legend of Zelda: A Link to the Past (known in Japan as Zelda no Densetsu: Kamigami no Triforce
). This specific version is highly sought after by speedrunners and ROM hackers because it contains unique glitches and mechanics that were patched in later regional releases. ROM Technical Details
The following specifications define a clean, headerless dump of the Japanese v1.0 ROM: Internal Name : ZELDANODENSETSU Internal CRC : 3322EFFC : 03A63945398191337E896E5771F77173 : 8 Mb (1,024 KB) Compatibility and Use Cases Randomizers : This ROM is the required base for most A Link to the Past Randomizer
(ALttPR) seeds. If your file has a different CRC, it likely has a "header" (extra metadata at the start) or is a different version; tools like the ALttPR CRC Checker can help verify and strip headers to make it work. Speedrunning
: Speedrunners prefer 1.0J because it allows for exclusive tricks like Spin Dashing Item Dashing Fake Flippers
. Using this version can save several minutes compared to English versions due to faster text scrolling and these movement glitches. Practice ROMs : Many practice hacks, such as those found on
, are specifically designed to be patched onto a 1.0J headerless ROM. Verification Tips If you are struggling to get a patch or randomizer to work: Remove the Header
To work with the Zelda no Densetsu: Kamigami no Triforce (J) (1.0) ROM—specifically the one with the CRC32: 3322EFFC a link to the past j 10 rom with crc 3322effc work
—you generally need to ensure the ROM is "headerless" for it to be compatible with most modern randomizers and ROM hacks. 1. Verify Your ROM Checksum The checksum
is the definitive identifier for the Japanese 1.0 version of A Link to the Past Verification Tool ALttP CRC Checker to upload your file and confirm it matches this code. Version Importance
: This specific version is highly sought after by speedrunners because it contains exclusive glitches, such as fake flippers item dashing , which were patched in later releases. 2. Remove the Header (If Needed)
Many ROM files dumped from cartridges include a 512-byte "header" that interferes with patching. : If your file size is exactly 1,049,088 bytes , it has a header. If it is 1,048,576 bytes , it is headerless and ready. : You can use the ALttPR Game File tool to automatically remove the header if one is detected. 3. Patching for Randomizers or Hacks
If your goal is to play a randomizer or a specific ROM hack (like or a practice hack), follow these steps: Get a Patcher : Download a tool like Lunar IPS (LIPS) Apply the Patch Open the patching tool. Select the patch file you downloaded (e.g., from Romhacking.net Select your verified 1.0 J ROM Web Randomizer A Link to the Past Randomizer
, you simply upload your 1.0 J ROM directly to the website to generate a new playable seed. 4. Why This Version? Benefit for Players Speedrunning Fastest version due to glitches like Spin Speed Randomizers Required base ROM for almost all ALttP Randomizer Standard base for technical hacks like the ALttP Practice Hack Are you trying to set up the Randomizer specifically, or are you looking for a practice hack to learn speedrunning glitches?
The ROM file with the CRC 3322EFFC is the specific hash for the original Japanese v1.0 release of The Legend of Zelda: A Link to the Past (known in Japan as Zelda no Densetsu: Kamigami no Triforce). CRC 3322EFFC identifies the original Japanese v1
This particular ROM is highly sought after because it contains several unique glitches and behaviors that were patched in later revisions (v1.1, v1.2) and the international (US/PAL) releases. 🎮 Why This Version "Works" for Special Uses
This ROM is the "Gold Standard" for specific communities due to its unpatched state:
Speedrunning Advantage: It is the only version that allows for "Fake Flippers" (entering water without the Zora Flippers), "Item Dashing", and "Spin Speed". These glitches can save several minutes in a competitive run.
Randomizers: Many popular randomizers, such as the ALttP Randomizer, require this specific Japanese v1.0 ROM as a "base" to build the randomized game file.
Source Code Projects: High-profile reverse-engineering projects that port the game natively to PC (C++ implementations) often use this exact ROM as the asset source. 🛠 Technical Specifications
To ensure you have the correct file, you can verify it using these identifiers: Attribute Region Japan (NTSC-J) Version 1.0 (Original Release) CRC32 3322EFFC File Type

If you are playing this version for the first time, you will notice several differences from the standard English version:
The CRC 3322effc corresponds to the Japanese (J) version of The Legend of Zelda: A Link to the Past (SNES), often named:
Zelda no Densetsu - Kamigami no Triforce (Japan).sfc or .smc
This CRC is known from No-Intro and GoodSNES sets. To find a verified copy:
Important note:
Some versions have a 512-byte copier header (CRC changes). The CRC 3322effc is for a headerless ROM. If you find one with a different hash, you can remove the header with a tool like TUSH or SNES Tool.
For emulation, any modern emulator (SNES9x, bsnes, Mesen-S, RetroArch) will run this file perfectly once matched.
If you already have a ROM with a different CRC but believe it's the same game, run it through a hash checker (e.g., certutil -hashfile on Windows, shasum on Mac/Linux) to compare.
Later revisions (1.1 and 1.2) introduced rudimentary copy protection. While these are easy to bypass, the 1.0 Japanese ROM has zero anti-piracy checks. This makes it the most "compliant" version for RetroArch, Higan, and SD2SNES flash carts.
So you have the file. The CRC matches. But the emulator shows a black screen? Or a flash cart says "Unsupported File"? Here is why that happens and how to fix it.
