@NorthernLights Welcome, and thanks for submitting your first Wii dumps! 
Once your dumps get added to the database (first dumps will mostly take a day or two) you will be promoted to dumper and you can see the wii datfile AND all Wii discs through search (also explained in the Wii dumping guide)
If you want to know what games are undumped you can already check the PAL Wii undumped list:

I maintain the PAL Wii undumped list and the Wii dumping guide. If you also have NTSC Wii games please let johnsanc know, he maintains the NTSC undumped list. The Japanese Wii section is almost complete.
I will add your tip about the Dual Core and Unlimited Speed settings to the Wii dumping guide, THANKS for that!
@user7 Actually the PAL Wii undumped list is as up-to-date as can be (with the current knowledge of existing discs). There are probably a lot of 'revision/v1.01+' discs out there that we don't know of as they pop up quite frequently at redump.
Also, it is perfectly possible there are some Spanish titles not on the list, this can have multiple reasons:
1) Foremost, the titles on the undumped list are listed under their English names (eg. Survivor is called Supervivientes in Spain, so Supervivientes is listed as Survivor on the undumped list with the Spanish serial).
2) I don't know the existance of the Game
So, please let Diego know to look for the 4 letter serial on the boxart and check if that is listed in the undumped list. If the serial isn't listed on the undumped list and doesn't match anything in the redump database it is a new game. (And i would happily add it to the undumped list
