the most consistent reason why this doesnt work is that there is a space after the last letter when you type the name KONAMI_PES, best thing to do is go back in after youve typed the name and make extra sure there is no space, I think a space it automatically added after you finish typing so its worth the double check. I also heard that a mnimum of 10 songs is the best way to ensure the game reads the data, but the most important thing is checking there is no space, this absolutely done my head in for ages too as I could'nt figure it out, hope this helps.
