Try ripping the Image and using virtual disc drive software like daemon tools.
See? That's my only issue. Most console emulators that require ISO images don't have to go to a process of ripping an ISO, mounting them with Daemon tools, and then playing them. ePSXe, PCSX2, nullDC, and Dolphin doesn't have to go through this process. You just play the ISO files and that's it.
If only there was a Sega Saturn emulator that doesn't have this tedious process of installing ISO images, just to play them.
