Well, the output of GBSControl is not clear. I may have to get with them and see exactly what this means. LOL

Wait what do you mean "it's still outputting 60Hz"? 60Hz is normal.
Good point - rfancella, have you actually tried connecting the AVGA to a 15khz display like an old TV or arcade monitor?
The 15khz concerns horizontal frequency - not same thing as vertical refresh rate. ArcadeVGA outputting 60hz vertical is quite normal.
