So a year o more ago i build a cab with a crt monitor, i left it working with emudrivers and groovymame. The customer wanted to change the monitor for an lcd monitor, so kept the card for future use. Now , that im using the card im testing it with windows 7 64, and i had installed emudrivers with a no go, i get that 31htz split screen image, first i installed - Download CRT Emudriver & CRT Tools 2.0 beta 15 (Catalyst 12.6) for Windows 7/8/10 64-bits wi no luck , so i thought maybe i installed the wrong drivers so i tried Download CRT Emudriver & CRT Tools 2.0 beta 15 (Crimson 16.2.1 non-GCN* cards) for Windows 7/8/10 64-bits with the same result. My card its a radeon hd7450 and i recall last time all was straight and simple. What am i doing wrong? thanks for any help.
