A common piece of misinformation found on internet forums suggests that simply changing the file extension from .z64 to .iso will work.
Converting a Z64 file to an ISO isn't a standard procedure because they represent different storage mediums. However, users usually ask for this because they want to ensure their ROM is in the correct format for a specific emulator or flash cartridge. What is a .z64 File?
If you need to perform this task, it is likely for one of the three following reasons: 1. Packaging for Console Emulators (e.g., PSP/PS3) z64 to iso
While tools like IZArc and AnyToISO are excellent for converting between disc image formats like BIN, NRG, or CDI to ISO, they serve a completely different purpose. They have no functionality for handling N64 ROM files like .z64 . This is a crucial distinction to avoid confusion.

A proper ISO for a CD is 650 MB—far larger than any N64 cartridge (max 64 MB). If you create an ISO, you are adding hundreds of megabytes of padding. This is wasteful and often unnecessary.
Load the raw .Z64 files via an SD card using the appropriate emulator application. What is a
Here are the recommended methods to get your ROM into the right shape:
Emulators like RetroArch can read compressed .zip or .7z archives directly to save space, but only if the file inside uses a natively supported extension. If your target setup requires an .iso , unzip the file, perform the conversion steps above, and only re-compress it if your specific front-end explicitly permits compressed .iso structures.
