Hi, your submission is fine but if you want to do any future submissions (or redo this one, optionally), you can use MPF.Check on Mac with the following builds. The Mac builds for MPF do not get much testing so if you do get it to work (or something doesn't work) then let us know. It's a command-line tool only as the GUI is Windows only, but its pretty simple to use. Unzip MPF.Check and open the terminal in that folder, then run
./MPF.Check umd psp /path/to/dump.iso
MPF.Check will work with preparing submissions for other discs you may dump too, not just PSP.
