Also thoughts on this card? (R7 250)... want somehting with a LITTLE 3d oomph for some 3d accelerated emulation.
The only drawback i can see to that R7 240 is that it only does analog video from the VGA port, and the VGA port is connected by a ribbon cable, which might get a little video noise. I haven't actually used many mid range cards like that one, but it seems to be about 4x as powerful as a 5450, and the 5450 is a little underpowered for any 3D emulation. If you want modern 3D games you need something way more powerful again.
That's a great guide by buttersoft. I'm just getting into this stuff as well. I've taken my video feed from a Radeon card with crt_emudriver using an HDMI to Component converter. This works really well once I found the correct interlaced resolution from the added list.
My problem is that I can't get this working unless I'm using extended video settings across two monitors? If I disconnect my LCD Monitor from the setup I can't get a picture on the TV on PC boot-up that's not all messed up?
Cheers, man, happy to help. If you have a Radeon HD 5000 series or newer setup, the EDID emulation allowed by crt_emudriver can be turned on using VMM, but it only works with your card's analog video ports, IIRC. EDID tells windows what your monitor is capable of, usually in this case that it’s a 15kHz CRT. It locks that in, and windows doesn’t need to guess or default to anything on that port. In fact it doesn't even look at what the monitor says, it just uses what you've told it to. At the moment, however, your EDID is being provided by the LCD and then perhaps by the HDMI converter alone, and I think this is the problem. HDMI was never meant to carry SD video. But it’s difficult to diagnose what’s actually going on without being there. The converter might be meant to supplement an existing monitor, not replace it. With the LCD unplugged, have you tried booting up on an HD LCD TV? That might let you find out what resolution the HDMI converter is defaulting to.
An ideal setup would use analog RGB from the video card, into a VGA-to-component converter that gives a 1:1 conversion. This will get you better video quality, and would allow you to use EDID emulation as well.
TBH questions like this are better posted in the GroovyMAME forum, that’s the crt_emudriver support forum as well
Someone else on there might be able to shed more light.
