Some units run 64DD cart-conversion builds only; results vary by firmware/model. No hardware emulation. 64DD play typically requires cart-conversion builds, not raw disks.
Load speed ~23.8 MiB/s over microSD and USB-C. Varies by clone; not consistently published. “Fast loading” up to ~23 MB/s.
Max ROM / working RAM 64 MiB SDRAM + 16 MiB QSPI (2 MiB reserved) → effective up to ~78 MiB ROM coverage. Typically 64 MiB (depends on revision). 64 MB SDRAM.
Save handling Automatic write-back during gameplay (no reset ritual). Many clones require pressing RESET to back up saves to SD. Save without reset (auto-backup).
Supported save types EEPROM 4k/16k; SRAM 256k / 3×256k / 1 M; FlashRAM 1 M. Common N64 save types supported; behavior differs by firmware. EEPROM 4k/16k; SRAM; FlashRAM; RTC.
