A Link To The Past J 10 Rom With Crc 3322effc Updated May 2026

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.

Speedrunners and randomizer players often apply a small .IPS patch to 3322EFFC to enable QoL features (e.g., instant text, door randomizer, practice codes). When the patch is updated, the community says, "Update your 3322EFFC ROM with the new patch." The base ROM remains the same; the applied modification is new.

Let’s compare the three known Japanese revisions:

| Revision | Internal Rev No. | CRC32 | Known Differences | |----------|----------------|-------------|--------------------------------------------------| | Rev 00 | 1.0 | D202E094 | Original retail; contains “Yoshi” graphic glitch | | Rev 01 | 1.1 | A29B0D3A | Minor text fixes | | Rev 10 | 1.2 | 3322EFFC | Final official version; all known bugs fixed | a link to the past j 10 rom with crc 3322effc updated

Specific code changes discovered through hex comparison (using tools like vbindiff):

These changes are subtle, but for tool-assisted speedruns (TAS) and glitch hunters, Rev 10 is considered the “anti-cheese” version.

To understand the significance of this revision, we must first decode the filename conventions often used in ROM preservation.

Three communities drive demand for this exact hash: The "10" in the filename notation usually refers

For the uninitiated, a CRC is like a digital DNA signature. Among dedicated Zelda archiving projects (like the Zelda Reorchestrated and TCRF – The Cutting Room Floor), CRC 3322EFFC has been documented as belonging to a very specific build:

What makes 3322EFFC special is that it fixes several glitches present in earlier Japanese revisions (Rev 00 and Rev 01). Notably:

This revision is considered the most polished official Japanese release before the GBA port.

In the world of ROM preservation, filenames can be changed, but hashes do not lie. The CRC-32 checksum acts as a digital fingerprint. These changes are subtle, but for tool-assisted speedruns

When a ROM is dumped from a physical cartridge, it is run through an algorithm that produces a unique code. The code 3322EFFC is the specific identifier for the Japanese 1.0 version of A Link to the Past.

Why is this important? The US version of the game (often with a CRC of 63C4E329 for 1.0) is the standard for most players. However, the Japanese version with the 3322EFFC hash is preferred by certain communities for two main reasons:

The No-Intro project lists CRC 3322EFFC as the canonical Japanese ROM image. Every few years, bad dumps surface; this hash is the gold standard.
