The Critical Truth (2021 Edition)

In 2021, Dolphin Emulator (version 5.0-xxxxx and early 5.0-14xxx builds) had no native support for loading 7z files as executables. Unlike newer formats like RVZ or the older GCZ, the 7z file is purely a compression archive, not a disc image.

• Checksum integrity (CRC-32, SHA-1) for verifying dumps.
• Solid compression mode to treat multiple files (e.g., an update + base game) as a single stream.
