About

Yes, another Nintendo 64 emulator. This one, however, aims for perfect emulation by emulating the hardware inside of the Nintendo 64 itself, down to the register-transfer level (RTL). At the same time, I've tried to keep things as optimized as possible in hopes that CEN64 will someday run ROMs at full speed, even on modest systems.

Why?

CEN64 is my pet project. It's something I pick up whenever I get bored. To me, what Nintendo and SGI did with this console is nothing short of amazing. The ingenuity and design of the hardware was well-ahead of it's time, and it is an absolute blast to reverse-engineer and study. I started this project in order to learn more about what really went on at the hardware level back in the (good old) days.

Thank you to every single one of you developers for filling my childhood with excellent memories. I'd also like to thank the community on all their hard work and effort spent reverse-engineering this little gem. Without further ado... "Get N or get out"!

Build requirements

  • CMake
  • iconv
  • OpenAL
  • OpenGL

To build on Fedora 29, do: sudo dnf install cmake make mesa-libGL-devel openal-soft-devel

To build for Windows on Fedora 29, do: sudo dnf install cmake make mingw64-{gcc,iconv,openal}

To build for Windows on Windows XP..10, do:

  1. Install MSYS 1.0.11: https://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/msys-1.0.11/MSYS-1.0.11.exe/download
  • Say yes to post install
  • Say no to mingw is installed
  • Press enter a few times to finish the install
  1. Extract contents of "mingw64" directory to "MSYS\mingw" directory: https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/8.1.0/threads-posix/seh/x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z
  2. Copy "MSYS\mingw\bin\mingw32-make.exe" to "MSYS\mingw\bin\make.exe"
  3. Extract OpenAL "bin, libs, include" directories to "MSYS\mingw\x86_64-w64-mingw32" directory: https://openal-soft.org/openal-binaries/openal-soft-1.21.0-bin.zip
  4. Extract iconv to "MSYS\home\yourname\libiconv" directory: https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.16.tar.gz
  5. Run MSYS & type "cd libiconv" Enter, followed by "./configure --disable-shared" Enter, followed by "make install" Enter
  6. Extract CMake "bin, doc, man, share" directories to "MSYS" directory: https://github.com/Kitware/CMake/releases/download/v3.13.4/cmake-3.13.4-win64-x64.zip
  7. Extract CEN64 source to "MSYS\home\yourname\cen64" directory: https://github.com/n64dev/cen64
  8. Run MSYS & type "cd cen64" Enter, followed by "cmake-gui" Enter
  9. Add the "MSYS/home/yourname/cen64" directory to "Browse Source..." & "Browse Build...", then Generate MSYS compatible files:
  • Add OpenAL "MSYS/mingw/x86_64-w64-mingw32/include/AL" as "OPENAL/OPENAL_INCLUDE_DIR" & "MSYS/mingw/x86_64-w64-mingw32/lib/libOpenAL32.dll.a" as "OPENAL/OPENAL_LIBRARY" (if they are not found)
  • Make sure to use libiconv static lib (Not DLL) "MSYS/local/lib/libiconv.a" as "ICONV/ICONV_LIBRARIES"
  • Select "SSE4.1" or "AVX" as "Ungrouped Entries/CEN64_ARCH_SUPPORT" & make sure VR4300_BUSY_WAIT_DETECTION is ticked
  1. Click "Configure" then click "Generate" to get the makefiles, then quit cmake-gui, & type "make" Enter

Usage

  • How do I run cen64?
    You will need a valid pifdata.bin file (NTSC or PAL), & a ROM in .z64 format (in big-endian format).

To run cen64 without multithreading (slower):
cen64 pifdata.bin ROM.z64

To run cen64 with multithreading (faster):
cen64 -multithread pifdata.bin ROM.z64

  • How do I run 64DD games?
    You will need a valid 64ddipl.bin file (NTSC JPN or USA), & a 64DD disk image file in .ndd format.

cen64 -ddipl 64ddipl.bin -ddrom DISK.ndd pifdata.bin

  • How do I setup save files for games?
    N64 has various types of save formats used in games...
    You will need to specify the save type yourself, cen64 will create the file if it does not exist.

EEP4K:
cen64 -eep4k eep4k.bin pifdata.bin ROM.z64

EEP16K:
cen64 -eep16k eep16k.bin pifdata.bin ROM.z64

FLASH:
cen64 -flash flash.bin pifdata.bin ROM.z64

SRAM:
cen64 -sram sram.bin pifdata.bin ROM.z64

  • The game runs, but I get strange errors, like multiple ocarinas in Majora's Mask.

You can fix the issue by using the -flash option on the command line:
cen64 -flash flash.bin pifdata.bin majora.z64
