It was the freaking port.

I connected it to the second port and booted it up, then started playing around with the config again. Lo and behold, hdmi_group=1 didn't cause a catastrophic error! The rest was cake, thanks to you guys.

Very much appreciated, thank you so much for all your help!

@ballboff I got that done, but the text still flickers a little bit and also the lines flicker.

Don't know then. There may be some other setting that I'm missing, but you shouldn't need an adapter. The composite is designed for this purpose and you'd think the standard resolution would be suitable.
