Convert XDELTA to BIN

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 1, 2026
QUICK ANSWER
Is it possible to convert XDELTA to BIN?
Yes - XDELTA converts to BIN.

An .xdelta file is a binary diff, not a ROM. Feed it plus the exact original file into xdelta3 (or a GUI like Delta Patcher) and it writes out the finished .bin. You must have the correct unmodified source file or the patch will fail its checksum.

Also to BIN: B64 · HEX · VCD

Why convert XDELTA to BIN?

xdelta patches are tiny because they only store the differences between an original and a modified file, so distributing a .xdelta is far smaller than sharing a whole ROM. Applying it reconstructs the full modified file, which for many consoles carries a .BIN extension.

How to convert XDELTA to BIN

Delta Patcher EASIEST

Open Delta Patcher, set the original ROM under "Original file", pick the .xdelta under "XDelta patch", and click Apply patch to write the patched .bin.

xdelta3 (command line) FREE

Run xdelta3 -d -s original.bin patch.xdelta output.bin to decode the patch against the source and produce the output file.

xdelta UI FREE

Use the xdelta UI front end to select the source file and patch, then apply so it saves the resulting file with your chosen .bin name.

.XDELTA xdelta Differential File

An .xdelta file is a binary patch created by the xdelta tool that records only the differences between an original file and a modified version. It is not meant to be opened and read…

.BIN CD/DVD Disc Image (BIN/CUE)

A BIN file is most often a raw, sector-by-sector copy of a CD or DVD that ships with a matching .cue text file describing the tracks. Mount it with PowerISO or DAEMON Tools Lite (point them…

Quality & what to watch

  • The source file must be byte-for-byte the exact original; a wrong region or bad dump makes xdelta3 abort with a checksum error.
  • The .bin extension is just a label - the real output is whatever file type the patch author diffed, so you may need to rename it (e.g. to .iso).
  • Nothing is lost in the patch itself, but distributing patched ROMs can be a copyright issue, which is why only the diff is shared.

Frequently asked questions

Do I need the original ROM to apply an xdelta patch?
Yes. The patch only stores differences, so it must be applied to the exact original file it was created from.
Why does my patch fail with a checksum error?
Your source file does not match what the author used - a different region, revision, or a bad dump. Get the correct original.
What command applies an xdelta patch?
xdelta3 -d -s original patch.xdelta output decodes the patch and writes the output file.
Is the output always a .bin?
No. It is whatever file was patched; some are .bin, others .iso, .nds, etc. Rename to match if needed.
