I wrote to the moderator the following explanation.
"Hi, I don't understand why you move my thread to the hall of shame. If you read my thread thoroughly, I was asking why the PSP would not boot the game "FROM THE UMD DRIVE" not "FROM THE MEMORY STICK". I was trying to make the PSP "READ THE BOOT FILE" from the memory stick and "EXECUTE THE GAME" from the UMD disc which is inserted in to the PSP."
Back to the original topic, any thoughts of why it won't work? (the question from my thread)
I think it worked for me once, but I didn't pursue it because it seemed like an exercise for which I could never get back the time I spent. In other words, there was no value to it. (I didn't want to boot games off memory stick anyway, even if ultimately it was to access the game from the UMD drive).
Perhaps you should explain why you want to do this. That will probably determine whether this thread stays open or is closed again.
