Xbox dev mode: need help accessing retail saves

Being the tech idiot that I am, I finally got dev mode and my emulators and old roms all working. I followed through johnnypapercuts instructions to access retail mode saves and save states, copied them over to USB, but I still can only start new games and fail to load any save states when in the roms.

Does anyone have an idea of what I screwed up, or is there a different way I should try to access saves?

Everything seems to be running through Q drive right now. Should I just switch to E drive? Does my system just look in the wrong place for save files when I boot a rom?

Thanks in advance!
