Does anybody succeeded to recreate 400i or 576i or 480i resolution on CRT@15KHz?
I'm trying to output with that resolution because I need that for SCUMMVM (the MisterFPGA native solution, not the one in ao486).
I know that the output is supported because I have no problems with the amiga core (the core can set the amiga "hi-res" natively in vga_scaler=0 mode).
I tried:
video_mode=640,32,64,100,480,0.5,1,21.5,1309
but the image is scrambled.
The timings where taken from here https://www.arcadeitalia.net/viewtopic.php?t=2115
where I found:
modeline '640x480' 13,09 640 672 736 836 480 481 483 526 interlace -hsync -vsync
and used this https://www.epanorama.net/faq/vga2rgb/calc.html to convert the numbers.
Thank you in advance.
