Binary Patch Generator

01 / Tool workbench

Use the runtime only when it is actually ready.

The application shell fails closed. An input interface is not enabled merely because a WordPress Tool record exists; the declared engine must be registered in the current build.

Binary Patch Generator

BROWSER LOCAL

Checking whether the declared runtime module is loaded. No input has been processed.

Session change summary

No output has been built in this session.

What this patch tool does

Create deterministic BPS or classic IPS patches locally from an original file and a modified target file.

Format and input contract

Both source and modified target files are limited to 8 MiB. BPS is generated with source, target, and patch CRC32 values. IPS generation uses classic 24-bit offsets and the optional three-byte final-size extension when source and target sizes differ.

Integrity and compatibility limits

The BPS generator uses a deterministic linear SourceRead/TargetRead strategy rather than claiming globally optimal patch size. IPS has no embedded source checksum and can silently produce incorrect output when applied to the wrong base file.

Browser-local processing

When operational, Phase 20 reads only files explicitly selected in the browser, enforces bounded buffers, and does not silently upload patch inputs or outputs.

02 / Compatibility

Know the supported input before opening a file.

Compatibility fields are intentionally explicit. Missing values stay unclaimed rather than being filled with generic assumptions.

Accepted extensions

.bps.ips

Platforms

No platform assignment is recorded.

Supported versions / editions

Modern evergreen browsers with JavaScript, Uint8Array, Blob, File.arrayBuffer(), and URL.createObjectURL(). Phase 20 bounds source, target, patch, and output files to 8 MiB.

Input constraints

Both source and modified target files are limited to 8 MiB. BPS is generated with source, target, and patch CRC32 values. IPS generation uses classic 24-bit offsets and the optional three-byte final-size extension when source and target sizes differ.

Known limitations

The BPS generator uses a deterministic linear SourceRead/TargetRead strategy rather than claiming globally optimal patch size. IPS has no embedded source checksum and can silently produce incorrect output when applied to the wrong base file.

Output / result

A downloadable BPS1 or classic IPS patch. Generated BPS output includes CRC32 checksums; generated IPS output contains only standard IPS records/footer behavior.

03 / Instructions

Use a reversible workflow.

File-oriented workflows start with an untouched original. Tool-specific instructions add only details documented for this utility.

01Keep the original
Preserve an untouched copy before creating or transforming binary output.
02Confirm scope
Match the file size, format, platform, and version to the support information on this page.
03Process locally
Use the runtime only when the page reports that its declared engine is loaded.
04Validate output
Compare or test the result before replacing any working source file.

Tool-specific steps

Choose the untouched source and modified target, select BPS or IPS, generate the patch, then verify it by applying it to a copy of the original before distributing it.

04 / Privacy and processing

The processing mode is part of the product contract.

SaveEditor.com should state local processing only when the implementation truly keeps file contents in the browser. Server or hybrid processing must be disclosed just as clearly.

Tool-specific privacy notes

Phase 20 patch generation and application are browser-local. Selected source, target, and patch files are read only after explicit user selection. This runtime contains no fetch, XMLHttpRequest, WebSocket, or sendBeacon calls. Source/target/patch/output buffers are each bounded to 8 MiB.

05 / Troubleshooting

When a file is rejected, do not force it.

A rejection can indicate an unsupported size, format, version, platform, or byte sequence. Preserve the original and correct the input instead of bypassing validation.

Wrong file or size

Re-check the documented input type and browser size limit before retrying.

Unsupported format

A generic converter does not imply support for every game-specific container, signing scheme, or serialization format.

Source was modified

Return to the untouched source instead of repeatedly processing a damaged or partially transformed file.

Known Tool issues

If IPS generation exceeds format or browser bounds, use BPS. If a generated patch is unexpectedly large, confirm the two files are truly related and do not contain unrelated shifts or container-level rewrites.

06 / Verification

Support claims should be traceable.

The verification date, method notes, and public references are kept separate from marketing language so compatibility can be reviewed over time.

Method notes

Verified by deterministic Phase 20 BPS/IPS generation vectors, independent BPS reference decoding, IPS RLE/truncation fixtures, checksum-corruption tests, malformed-input rejection, and 8 MiB boundary tests.

07 / FAQ

Questions to answer before editing.

These answers are generated from the Tool record and current runtime state rather than generic compatibility promises.

Is Binary Patch Generator ready to use?

The Tool record is verified and declares an operational runtime. The page enables its input controls only when the declared engine module is loaded in the current build.

Does processing stay in the browser?

Yes for this declared mode. The loaded runtime processes the explicit input in the browser; Tool-specific privacy notes describe the exact scope and limits.

Should I keep the original file?

Yes. Keep an untouched source file until any generated output has been validated.

What if my input is rejected?

Use the validation message to correct the base, encoding, width, timezone, byte alignment, or size. The runtime does not guess through invalid input.
