**THIS IS FOR THE D2CPRO GW-601**
so after about a week and a half of struggling with getting this game to work i finally did; i tried everything, patched isos, original isos all burned to every kind of dvd-r i could find (running a d2cpro gw-601).
then i went to my cousins place and tried all the backups i had made at his place and every single one worked, the patched and unpatched ones; i immediately uninstalled the d2c-pro and each game worked perfectly (softmodded 4.2u wii).
now when i say perfectly i mean that each dvd was recognized as NSMB Wii by the neogamma channel even if they didn't start correctly - this was a huge jump from the no disc error that i had constantly been getting with the d2cpro gw-601 chip installed, both in the disc channel and neogamma channel.
so for all of the peoples who are unfortunate enough to have a wii chipped with a d2cpro gw-601 youre screwed (if you want to run the game via dvd).
the only way you can run the game is if you have an external usb hdd and run it that way.
(if this has been posted already by some one else i appologise - i had looked every where for a hint/support in the d2pro modchip sectino and everywhere else, search functino and everything but no luck >.< all i could really deduce from the d2pro section (and google was there were others like me >.<).
hope this helps any one that is lost with a d2cpro gw 601 >.<
