Thanks, Isn't it strange that with no SD card inserted it comes right up on the TV? Thats what has me so confused and it used to work fine on my RCA TV. I never have been able to get it working on the Bravia or Samsung. I had done that before, but I used Escher. MAybe that's the issue. I'll flash with the official one.
@iamtyce@DougA I finally managed to solve the problem with an HDMI splitter and an HDMI-to-VGA converter. 😄 The latter doesn't change the resolution, but my projector accepts the analog signal in contrast to the digital HDMI signal, which it refused as "unsupported". I just had to adjust the picture a bit via the projector's controls, as it was slightly off to the left and only partly visible.
A mentionable obstacle was that only one out of three HDMI splitters I tried worked with the 1600x1200 pixels DMT signal from the Pi. The other two only accepted CEA signals (see HDMI mode options in the official Raspberry Pi documentation). Strangely enough, all three splitters look exactly the same from outside apart from the brand logo.
By the way, video signal on cps2 arcade machine was indeed 16:9, but the rendering was on a 4:3 screen. Rendering cps2 games as 16:9 is a bug, it was fixed on lr-fbalpha in late 2015, and was backported to lr-fbalpha2012 a few months ago.
About using the old lr-fbalpha2012 because you got the wrong roms, why not update your roms instead ? If you buy the wrong tire for your car, do you buy a new car or do you go back to get the right tire ? I can understand using lr-fbalpha2012 on a raspberry in a few specific cases (i'm mostly thinking about svg and killbld here), but lr-fbalpha is overall better because a lot of bugfix and compatibilty was added in the last 5 years.
Long time i used a LCD screen, has build an upright cabinet for it, spent hours and hours to find nearly realistic shaders... but at the end i use an old crt. So there are no latency problems cause of upscaling, no stuttering, and the result looks fantastic ;-)
