I need help. When I try to play Metal Gear Solid on ePSXe, in game I cannot switch frequencies. The only thing I can do is press down to see the ones I've already got. Is this a ROM thing or is there some sort of configuration that will let me see the frequency I am trying to dail on my codec?
I am running Pete's D3D video driver 1.76, and ePSXe CDR WNT/w2k core 1.5.2. I am running the latest version of ePSXe which is 1.6.0.

Thank you to anyone that helps me.
