I'm not sure, "afs_data.afs" opened fine for me. Maybe try using AFS Packer instead to see if that resolves the problem?
Also, "slpm_651.40" is not an extractable file, disregard it.
Edit: Upon further inspection of the extracted files, some of the ones from "afs_data.afs" seem to contain TIM2 images, but I can't extract them correctly. It seems they are stored in the .pzz files from "afs_data.afs", and are meant for use in cutscenes.
