I followed the existing guides and tutorials in this forum. I've heard that the alt dol method for metroid prime trilogy is outdated. I installed d2x v7 final on both 249 and 250 and still cannot get it to work. I've set block reload iOS to on and when I try to play metroid prime trilogy it returns me to the system menu. I own the PAL version of this game but had my friend send me a back up of his NTSC version. thats the one I'm currently trying to load. I also have the same issue with Metroid Other M, both are my friends back ups of PAL games I own. (my wii is NTSC i got a good deal on the games thinking they were NTSC only to find out they were PAL when I got them in the mail.)
Have you looked HERE?
It could be bad backups as well. You can use your pal discs since you are usb loading anyhow.....rip those and follow the guides.
It says the link is invalid I will try to install the PAL version of MPT and see if it works.
edit: I looked at the URL bar and yes I have tried to use that guide to get MPT to work but it won't let me boot any alt dol it returns me to the system menu.
edit: I guess it was my back up, I am using a mac and used Backup Fusion to split the wbfs file.
