Hacking Finding out what Modchip you have

[Cubewood]

Hi,
A friend of mine has a Wii with modchip, but she don't know wich modchip she has. Now she is trying to get Mario Galaxy working, but I think she needs a firmware update. Thing is she don't know what modchip she has, since someone else have modded it for her.

Is there any way to find out what modchip she has without opening the case ?

Thanks
