Thanks Torange!!! NSMB working flawlessly...
Just want to post and let everybody know this guide worked perfectly :D
I'm a new member and started searching online for a solution as I purchased a backup copy that plays for 10-15 mins before a black screen pops up to prompt a reboot.
I followed this guide last night (although there's a few steps that need to be updated as mentioned by other members) and got the game working. Here's my system setup:
4.1u + D2Pro Chip + HBC
Now all I have to do is load the NSMB via DVD with Neogamma and have been playing for hours with no issue.
Thanks again for OP and all who posted helpful finds.
Happy Holidays everyone!! :p
