|First open screenmode in Prefs and test all the resolution available with your Monitor.|
My Monitor doesn't accept 304 x 224 as well as other SAGA resolution, so I have to use an DIGITAL-VIDEO scaler to see the NeoGeo screen.
If the screen is compatibile then the problem is in the GnGeo which has not been tested on V1200. Sorry.
