Marvel Vs Capcom for PSX eboot problem

I'm trying to get the file to run on my PSP but the file shows up corrupted. I'm using 5.00 M33-6 firmware on the PSP and use SImple POPstation GUI 2 Beta to convert the files into an eboot file. DOes anyone know why this might be happening?

The name may be too long when you convertid it. When it asks you to name it keep it less than 12 characters as with the folder that you keep it in.
