Wasabi DX, problems with NSMB
Hello. I bought an European Wii almost 2 years ago. Then, I installed a Wasabi DX chip, and I've been able to play PAL backups perfectly, until I tried with New Super Mario Bros.
My Wii version is 3.4E (I upgraded it once, almost by mistake last year, but never again), and when I got this problem with NSMB, upgraded my Wasabi DX to v3.0 (a few days ago). After having patched the untouched NSMB ISO with BCA fix (downloaded from Wasabi's official webpage), I tried it on my Wii, and it says I need to upgrade it.
What should I do? Should I upgrade my Wii again? I've heard it may be risky or unnecesary.
I've been reading some threads, but I see that this info is not really up-to-date, or that people always end up recommending softmodding (I see it might have some advantages, but I still want to read much more before doing it; I'm kind of sceptical about it).
Is there any solution just using my Wasabi chip? I mean, upgrading, or patching the ISO, instead of installing additional software on my Wii... I'd like to make as few software mods as possible, at least for now.
Thanks a lot, and sorry for my ignorance.
