Yes, I don't have a modchip and don't want to use it (it's not my GameCube).
If I don't have other solution, I go to buy another SDML.

Thanks for your answer. I just discover this site and it's very helpful for me.

Hello,
I have a problem, my brother broke my SD Media Launcher disc.
Do you know if I can burn a disc with a software who can use this SD reader (without hardware modification) ?*
Thanks.
