Hacking Question about playing burnt Wii games (My Wii has a D2C-key)

[links1981]

So I got the Wii Modded with the D2C key years ago,

But around the time that Wii-Motion + came out the system updated Making the chip almost useless (Can only play burnt 3'ed party games....Shitty games)

Is there some kind of an update for the chip?
Can I fuck with the new Games (ISO's) to play on the chip?

Or do I have to Soft-mod the Wii and use a USB-HDD in order to play these new Nintendo games - (Nsmb,DKC, MG2....)

My Wii is on the newest FW (4.3U I think?)


PS. I have TRIED to soft-mod my Wii and I just cant do it (or maybe the guides are to Complicated?) ... I would rather just burn the games to DVD and play
What is the D2C-Keys Site? - Maybe theres a update on it?
