First thing's first, I'm well aware of PRO cfw and ME cfw and I know both of them can load psp backups straight through the vsh(xmb) but I'm curious to know which one is the best in terms of compatibility?
Open idea iso loader?
Promtheus? (not sure if it's spelt correctly)
Or eloader? I don't remember the name.. I think it had something with 'a'
