How to Play an ISO on Devhook

DevHook is a homebrew firmware emulation software. Original PlayStation Portables run firmware 1.50. The DevHook emulation installs on the PSP memory card and allows the user to emulate higher firmware versions. This emulation allows the PSP to run newer firmware games without upgrading the 1.50 original firmware. DevHook also allows users to mount and play ISO/CSO game files directly from the memory card.
