Adaptateur N64 to GC 1.0

Qu'il soit possible de jouer aux jeux N64 sur la Wii est une chose merveilleuse (Merci Nintendo!), mais naturellement, l'expérience est bien plus authentique avec les vraies manettes d'origine.

Ce billet est un portage du circuit développer par Raphaël Assénat (raphnet technologies).
Raphaël utilise une carte générique de sa conception pour son adaptateur. J'ai volontairement limité ma carte au strict minimum de composant. Je n'utilise donc pas son Multiuse tiny1 PCB.

Voici donc le schéma du PCB:

La puce Atmega8 doit être programmée avec l'un de ces firmewares:

Controlleur	Version	Fichier	MCU	Commentaires
Nes/Snes	1.3	snes2wii-1.3.hex	Atmega8	Changes in this version: Added a feature to swap the NES A and B buttons. Hold A and B at power up to use it.
Nes/Snes	1.1	snes2wii-1.1.hex	Atmega8	Changes in this version: NES mode can be forced on by holding the Start button at power-up. Without this, in my opinion, NES games are almost unplayable with an SNES controller. Implemented button combinations which can affect how unaccessible Gamecube buttons and sticks are reported. eg: Sending L+R pressed with a NES controller, and sending "CStick towards the right". Mostly useful to summon some emulator's menu while playing. Implemented new Gamecube commands for better compatibility, eg: GCLinux.
Nes and Snes	1.0	snes2wii-1.0.hex	Atmega8	This was the first version. Nes or Snes mode selected with jumper.
Nintendo 64	1.4	n64_to_wii-1.4.hex	Atmega8	New in this version: Added 4 new button mappings, accessible by holding a C button for each mapping. These are reported to be useful for Super Smash bros Melee and Brawl. Created a single page PDF documenting the supported mappings.
Nintendo 64	1.3	n64_to_wii-1.3.hex	Atmega8	New in this version: It is now possible to disable the feature where the L and Z buttons are swapped by holding the 'L' button down when plugging the adapter in the console. If the R button is held down when plugging the adapter into the console, the N64 C-left and C-right buttons are mapped to the Gamecube Y and X buttons. This makes it possible to play the virtual console game Sin and Punishment. The joystick sensitivity can be increased by holding the Dpad right button when plugging the adapter into the console. The joystick sensitivity can be decreased by holding the Dpad left button when plugging the adapter into the console.
Nintendo 64	1.2	n64_to_wii-1.2.hex	Atmega8	Version 1.1 for N64 had a reliability bug which caused some controllers to randomly reset and recalibrate during play. This is fixed in version 1.2. It is recommended that you upgrade even if version 1.1 is working for you.
