Hello,
Thank you @niuus for your tutorials, well explain
I took a little time to understand how it works for Sonic CD, but looking here, I quickly understood my mistake ==>https://github.com/niuus/Sonic-CD-11-Decompilation/releases
Sonic CD works on my wii console and on my wii U console.
and thank you also to all the other members on this page for the explanations.
