Apologies for another 'I can't figure it out' post. My old brain is literally melting and I can't sleep for trying to figure it out!!
I have a UK/Europe Sony BVM 20G1E (recent purchase), an old Lenovo M93p with an ATI/AMD Radeon HD 6450 1GB graphics card.
The computer is attached to the monitor via DVI-I into a VGA adapter and then VGA to 5 BNC (I also have a 4 BNC lead).
Switchres installed fine and can see my AMD.
Starting up CRTEmu and the only monitor pre-set that doesn't cause the screen to roll is NTSC TV 60HZ. I select this one and then when generating modelines (using super.ini) it gives me 5 to install (it does say 26 redundant video modes found).
When I try and run a game via Groovymame for example, Outrun video mode is 320 x 224 (H) 60.05439 Hz and Switchres is 2560 x 240p 59.940 kHz the games will start to vertically roll very slowly.
If I run via Groovymame for example, Super Sprint video is 512 x 384 (H) 60.096153 kHz and Swithres is 2560 x 480i 59.940 Hz 15.734 kHz the game runs fine.
Would I be right in thinking I have a problem with games displaying at 240p?
I can usually figure this stuff out via research, tutorials etc and really don't want to be a bother, but if someone can shed some light on what I'm doing wrong I would be super grateful!
I've included some pics and videos that might help?
Many thanks.
