I want to play wii games on my softmodded wii version rvl 1 and on software version 3.1u
Is it possible??
If you are still on 3.1, no doubt your mod is out of date. See the softmod Any Wii guide to get it current.
After that, see the FAT32 or NTFS guides to learn how to get your hard drive ready to play games off of it.
All guides mentioned above are linked in my signature.
Will I able to mod my wii after updating as it is an old console??
If you are asking questions like this, you didn't read the guide.
I guess the older console, the better it is for modding, isn't it?
Launch-year units have the Boot2 vulnerability which has the best brick recovery since a NAND backup can be restored through bootmii.
But any Wii other than the new Wii Minis can be modded and used for USB loading.
