InfoNES64

A Nintendo Entertainment Emulator running on th Nintendo 64. Run it on real hardware using a flash drive, or an emulator.

Note

This project is more of a fun thing for me to try if it works. It runs way too slow to be really usable and playable. I don't know if the emulator will ever run at full speed. Help is always welcome.

It has a unlicensed built-in game "Blade Buster", but you can replace it with your own game. See below.

Built with Libdragon

Controls

• D-Pad: Move
• A: Button A
• B: Button B
• Start: Start
• Z + A : Toggle frame rate display
• Z + R : Toggle sound (default off)

The emulator code is ported from Infones by Jay Kumogata

Release

To try the emulator with the free built-in game Blade Buster, download infones64.z64 from the releases page en copy it to your flash card.

Building from source

1. Install the Libdragon SDK. For more info and instructions, see https://github.com/DragonMinded/libdragon
2. Make sure the environment var N64_INST points to the installed SDK
3. Get the sources and build

git clone https://github.com/fhoedemakers/InfoNES64.git
cd InfoNes64
make

Then copy infones64.z64 to your flash drive.

Replace the built-in game with your own rom

One of the ways to do this is:

1. xxd -i myrom.nes > myrom.c
2. Copy myrom.c to the assets folder
3. edit myrom.c

// Change the define
#define BUILTINROMNAME "myrom"

// Change murom_nes[] to builtinrom[]
unsigned char builtinrom[] = {
  0x4e, 0x45, 0x53, 0x1a, 0x10, 0x10, 0x42, 0x00, 0x00, 0x00, 0x00, 0x00,
  0x00, 0x00, 0x00, 0x00, 0xa9, 0x08, 0x8d, 0x00, 0x20, 0xa9, 0x00, 0x8d,
  0x01, 0x20, 0x20, 0xd6, 0xe1, 0x20, 0xeb, 0xe2, 0xa9, 0x00, 0x20, 0xe6,
  0xd0, 0xa0, 0x0c, 0x84, 0xe

...

 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
  0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
  0xff, 0xff, 0xff, 0xff
};
// change variabele from myrom_nes_len to builtinrom
unsigned int builtinrom_len = 393232;

4. Edit builtinrom.c

Insert

#ifdef BUILTINROM_MYROM
#include "myrom.c"
#endif

as shown below

#include "builtinrom.h"
#ifdef BUILTINROM_BLADEBUSTER
#include "bladebuster.c"
#endif
#ifdef BUILTINROM_SMB3
#include "smb3.c"
#endif
#ifdef BUILTINROM_GALAGA
#include "galaga.c"
#endif
#ifdef BUILTINROM_CV1
#include "CV1.c"
#endif
#ifdef BUILTINROM_CV2
#include "CV2.c"
#endif
#ifdef BUILTINROM_CV3
#include "CV3.c"  // not working
#endif
#ifdef BUILTINROM_MYROM
#include "myrom.c"
#endif

5. edit builtinrom.h

#pragma once

// Specify the name of the built-in ROM to include
#define BUILTINROM_MYROM
extern unsigned char builtinrom[];
extern unsigned int builtinrom_len;

#ifdef __cplusplus
extern "C"
{
#endif

char *GetBuiltinROMName();
#ifdef __cplusplus
}
#endif
