I checked and it says. "Redirect the apps roms reads to a file on your sd card. The file should be standard romfs partition." What does that mean?If it says invalid when you select "Yes" for "SD -> romfs" (or was it romfs -> SD?), make sure that you named the romfs file in the "hans" folder correctly.
Open up your cartridge in HANS, turn on "SD -> romfs", and read the text at bottom of the top screen. Although, this is assuming I'm guessing your situation right.
The screenshots_raw.bin is normal.
