Developed by the Dolphin Emulator team, RVZ is a highly compressed, lossless disc image format. It replaced the older GCZ and CISO formats.
Advantages of RVZ:
The Catch: Outside of Dolphin, RVZ is virtually useless. You cannot burn an RVZ to a DVD for a real Wii, load it onto a USB drive for a Wii or Wii U, or run it in older emulators like PCSX2 (for PS2) or standalone Cemu (for Wii U).
Cause: You are using an old version of Dolphin (pre-5.0-12000). The RVZ spec has evolved. Fix: Download the latest development version of Dolphin from the official site.
The syntax is simple:
dolphin-tool.exe convert -i "input.rvz" -o "output.iso" -f iso
For Batch Conversion (Entire Folder):
for %i in (*.rvz) do dolphin-tool.exe convert -i "%i" -o "%~ni.iso" -f iso
Pro Tip for Speed: Add -b 2097152 to increase block size for faster writes.
