I got here a bricked wii with a black screen and no modchip inside.
I got the original Yu-Gi-Oh! 5D's Wheelie Breakers.
If i bought me a savemii or use a gamecube controller to enter the recovery mode is it possible with yu gi oh to fix this wii or need i a modchip to run yu gi oh?

 

I got the wii from a friend and he bought it online and he hopes to fix it.
I tried and no bootmii or priiloader on it.

But i want to know if yu gi oh original exploit works with safemii without having a modchip.

 

I think if it is an original dvd your wii can start it without a modchip in the recovery mode(i think it work without autoboot(?)).

But if it is a full brick you can not recover your wii with YGO because the recovery mode didn't work.

 

how are you planning to copy the hacked game save to the nand if the wii wont start? this exploit relies on that.

 

Getting a black screen directly (without any system menu artifacts)
Two common possibilities,

1 - Bluetooth module is broken or detached
a. solution: Replace defective bluetooth module or attach it firmly at it's place...

2 - A stub menu IOS is installed or menu IOS uninstalled completely
a. solution for an old wii that accepts bootmii@boot2 installation : flash bootmii using infectus

b. solution for a wii with keys and/or a nand backup (no bootmii@boot2 compatibility) : convert a healthy nand dump (donor should have same version of boot1) to said wii and flash it with infectus.

c. solution for a wii with no keys no nand backup and no bootmii@boot2 compatibility : currently none

A common method to see if it supports boot2 installation of bootmii is checking the original drive type of the wii using it's serial number (you can use wiidrives.com) If it has an older drivechip than D2C then it's 100% bootmii@boot2 compatible... if it has newer drive than D2C then it's 100% not compatible with bootmii@boot2... If it's a D2C you should check the cpu on the main board too see it for yourself...
