NES2Wii

NES2Wii - adapter for NES/SNES/N64/SMD/DualShock gamepad to NES Mini, SNES Mini or Wii remote

Features:

• You can play Wii virtual console games using original NES/SNES/N64/SMD/DualShock gamepad!
• You can use original NES/SNES/N64/SMD/DualShock controllers with NES Mini or SNES Mini
• You can connect Wiimote to PC via bluetooth and use original NES/SNES/N64/SMD/DualShock controllers with emulators

Schematics

Just ATMEGA16A (or any other low-power ATMEGA). You need 16MHz crystal for N64. 8MHz internal oscillator is fine if you don't need N64.

Fuses (for ATMEGA16 with crystal)

• Low fuse: 0xFF
• High fuse: 0xD9

How to use with PC

Just install HID Wiimote driver by Julian Lohr: http://julianloehr.de/educational-work/hid-wiimote/

Tested on

• ATMEGA16A, 16MHz crystal
• ATMEGA8A, 8MHz (without N64 support)
• NES, SNES, N64, SMD and DualShock controllers

Modes

There are three modes for NES/SNES/SMD controllers:

• Mode #1 - d-pad works as left analog stick and d-pad on classic controller at the same time
• Mode #2 - d-pad works as left analog stick only
• Mode #3 - d-pad works as d-pad only

You can hold Start+A+B for a few seconds to change mode. Red led will blink 1/2/3 times indicating new mode.

Notes

• You can select pins and required controllers in defines.h.
• Detect (DTCT) wire is optional but recommended to prevent some glitches. If not used it must be connected directly to VCC.
