you might have to google it DonZabu...
Then download ePSXe, because that's what most people are using.
It doesn't work that way. The second disk for Metal Gear Solid is MDF. It doesn't show up when you're choosing the cd image for the emulator.
Plus when I hit "Eject CD", the emulator freezes.
Based on your problems with discs, your virtual memory cards, and lockups it sounds like maybe you need to redownload a fresh copy of the emulator and install it to a new directory to see if that helps. Also consider it might even be your operating system/drivers causing the issue for whatever reason.
