Is it safe to use PatchVault?
Yes. Your files are processed entirely in your browser using the Web File API. Nothing is uploaded to our servers because we have no servers — the site is fully static.
What patch formats are supported?
IPS, BPS, and UPS patches are fully supported with native browser-side parsing. xDelta support is planned for a future update.
Can I use this on iPhone without a computer?
Absolutely. PatchVault was designed for Mobile Safari. You can patch a ROM or convert a save file directly on your iPhone or iPad.
Do I need to own the original game?
Yes. PatchVault is intended for use with legally obtained game backups. Downloading ROMs for games you do not own is illegal in most jurisdictions.
Why did my BPS patch fail checksum verification?
BPS patches are tied to a specific version of the base ROM (usually the USA v1.0 or a specific revision). Make sure you are using the exact unmodified ROM the patch was created for.
