Apply xDeltaPatches on iPhone & iPad
VCDIFF delta patching ideal for large NDS and PSP games where the diff is too large for IPS or BPS. Browser-side support is planned for a future PatchVault update. PatchVault lets you apply xDelta patches directly in Mobile Safari — no PC, no app download, and no account required. Your ROM file never leaves your device.
