ROM Compatibility & Hash Checker
Upload a ROM file or paste a hash to instantly compute CRC32 / MD5 / SHA-1 / SHA-256 and match against sample emulator compatibility datasets. Extend it with your own sources for deeper verification.
1. Compute Hashes
2. Match & Results
Built-in sample datasets for offline demo. Add your own remote JSON / plaintext lists (one record per line) to enhance accuracy.
Add Remote Dataset Source
JSON format: array of objects containing at minimum a hash field (md5 / sha1 / sha256 / crc32) + title. Plaintext: HASH | Title | Emulator | Status | Notes (pipe separated).
| Emulator | Title | Status | Hash | Notes |

About this Tool
This ROM Compatibility & Hash Checker was crafted to give players, archivists and emulator enthusiasts a fast, private, and transparent way to validate game images. Instead of uploading your ROM to a remote server, everything here runs locally in your browser using efficient Web APIs. The tool calculates multiple cryptographic and verification hashes (CRC32, MD5, SHA-1 and SHA-256) so you can identify exact revisions, bad dumps, or fan translations with confidence. A lightweight matching engine then compares those hashes with curated or user-supplied compatibility lists for popular emulators like Dolphin, PCSX2, PPSSPP and RPCS3. Because sources can vary, you can layer multiple datasets, inspect merged results, and export to CSV for record keeping.
How to Use
Drop a ROM file (ISO, BIN, WBFS, NSP, etc.) into the hashing panel. The progress bar shows streaming read status for large images. Once finished, hashes appear with quick copy buttons; enable or disable individual algorithms with the checkboxes to speed up processing for giant Blu‑ray images. Paste any external hash into the manual field to match instantly. To enrich compatibility coverage, open “Add Remote Dataset Source” and supply a raw GitHub, Gist or self‑hosted URL returning JSON or pipe‑separated text. All valid entries merge into an in‑memory index. Press “Export CSV” to download current match results for documentation or sharing in support forums.
Tips & Best Practices
For the most accurate verification, pair multiple hash types—SHA‑256 for uniqueness plus CRC32 for quick cross‑referencing on legacy lists. If a ROM does not match anything, try additional public datasets or confirm that compression (e.g. ZIP/7z) was extracted before hashing. You can maintain a personal preservation list by hosting a private JSON file and pointing the tool at its raw URL. Dark mode reduces eye strain during long cataloguing sessions; it remembers your preference locally. This single‑file implementation is intentionally framework‑free for speed, portability and easy WordPress (Kadence) embedding, outperforming bulkier online alternatives in load time and clarity. Extend it further by forking and adding checksum verification for multi‑file sets or integrating hash-to-Redump lookups (subject to licensing and API availability).
Why Hashes Matter & Privacy Promise
Hashes are like a digital fingerprint for your game file. Two files with the same hash are the exact same data, byte for byte. That helps you quickly tell if you have a good dump, a patched mod, or something that got corrupted during download or extraction. Using more than one hash adds safety: CRC32 is fast for quick community checks while SHA‑256 is very reliable for uniqueness. Everything here happens on your device only. Your ROM never leaves your computer and nothing is uploaded. That means you can safely check large disc images even when you are offline or on a slow connection. You can also add your own lists so the tool grows with your personal collection or preservation project. If you share the page with friends they can use it instantly without installing anything. Simple, private, and helpful.
