He is almost definitely not talking about sizes, but just to set the record straight:
All GC games that aren't multi-disc are 1.36GB
All single-layer Wii games are 4.38GB
All dual-layer Wii games are 7.93GB
These are the sizes Dolphin shows anyway; your file explorer might give you slightly different sizes due to rounding.
