       cen64 - Cycle-Accurate Nintendo 64 Simulator


       cen64 [Options] <PIF IPL ROM Path> [Cart ROM Path]


       CEN64  is  a  new  Nintendo 64 emulator which aims for perfect emulation by simulating the
       hardware inside the Nintendo 64 itself, down to the register-transfer level (RTL).  It  is
       still heavy under development and currently does not have any sound emulation.

       Being  a  cycle-accurate  emulator,  CEN64  has considerably high hardware requirements to
       achieve passable performance when emulating most Nintendo 64 titles. However,  similar  to
       the  higan emulator, the cycle accuracy guarantess very high compatibility and despite its
       early development stage, CEN64 already allows one to run several commercial titles without
       or with only minor glitches.

       As  a  distinctive feature among Nintendo 64 emulators, CEN64 offers emulation support for
       the 64DD external disk drive that was never released  outside  Japan  and  even  there  is
       considered  rare.  Thus, CEN64 offers the unique possibility for anyone to play any of the
       rare titles that were exclusively released on the 64DD.


       CEN64 currently supports only a very limited amount of options, a summary of these options
       is shown below.

       -debug [addr][:port]
              Starts the debugger on interface:port. By default, CEN64 uses localhost:64646.

              Profile the ROM (cpu-side).

              Run  in  a  threaded  (but  quasi-accurate)  mode. This mode cannot be run with the

       -ddipl <path>
              Path to the 64DD IPL ROM (enables 64DD mode).

       -ddrom <path>
              Path to the 64DD disk ROM (requires -ddipl).

              Run emulator without user-interface components.

              Run emulator without audio.

              Run emulator without video.

              IS Viewer 64 present.

       -controller num=<1-4>
              Controller with no pak.

              Pak options:

       -eep4k <path>
              Path to 4 kbit EEPROM save.

       -eep16k <path>
              Path to 16 kbit EEPROM save.

       -sram <path>
              Path to SRAM save.

       -flash <path>
              Path to FlashRAM save.
