The "10" in the filename notation usually refers to the internal ROM revision number (Rev 1). In the context of A Link to the Past, the original Japanese release was followed by later revisions (such as Rev 2) and the US releases (1.0 and 1.1).
The 3322effc version is distinct because it predates many of the bug fixes found in later cartridges. For glitch hunters, this is the "gold standard." It often contains specific exploits—such as item manipulation or out-of-bounds glitches—that were patched in later revisions. Running the 3322effc ROM ensures that these aspects of the game engine remain accessible, allowing players to interact with the game’s code in ways the developers originally left unchecked.
The original dump of Rev 10 was made in 2012 from a late-production Super Famicom cartridge (model SHVC-24, serial number starting with “2H”). However, the “updated” tag in your keyword likely refers to a 2020-2021 redump effort:
Thus, when you see “with CRC 3322EFFC updated”, it typically means: the verified, 2021 redump from the Nintendo Power source, not the 2012 cartridge dump. a link to the past j 10 rom with crc 3322effc updated
To understand the significance of this revision, we must first decode the filename conventions often used in ROM preservation.
The #1 reason to hunt for this exact CRC. Check any record on speedrun.com for A Link to the Past – the rules state:
"Must use the Japanese v1.0 ROM. Verified CRC: 3322EFFC" The "10" in the filename notation usually refers
Using an English ROM or a patched Japanese v1.1 will lead to leaderboard rejection.
Let’s look under the hood. Using a hex editor or emulator with debug features, here is what you will find:
| Property | Value | |----------|-------| | Full Title | Zelda no Densetsu: Kamigami no Triforce (ゼルダの伝説 神々のトライフォース) | | File Size (Unheadered) | 1,048,576 bytes (exactly 1 Mbit / 8 Mbit) | | CRC32 (No-Intro) | 3322EFFC | | MD5 (Expected) | 2d510d2c8f5144c2f6c1afe078eb979b | | SHA-1 | 71b26d5b4a0337444615114b53f9b280f9af0da9 | | Internal ROM Speed | FastROM (2.68 MHz) | | SRAM Size | 64 Kbit (8 KB) – for save files | | Map type | HiROM (bank $40-$7D) | | Version | v1.0 (No revision number in header) | Thus, when you see “with CRC 3322EFFC updated”
In the vast world of retro game preservation, few things excite collectors, speedrunners, and ROM enthusiasts more than a verified, rare revision of a classic title. For over a decade, The Legend of Zelda: A Link to the Past has been analyzed down to the smallest byte. However, the specific file known as "A Link to the Past J 10 ROM with CRC 3322EFFC updated" has recently become a hot topic in preservation circles.
This article will dissect everything you need to know about this particular ROM revision: its origins, why the CRC (Cyclic Redundancy Check) hash of 3322EFFC is critical, what “Rev 10” means for the Japanese version, and where this “updated” release fits into the Zelda timeline.
