[advancemame-users] SVGALIB 320X240 on hantarex polo

[Martijn <Adv...@ga...>]

I'm having trouble to get a stable picture for 
ntsc_320x240/standard_320x240/pal_320x240 modes in advv. I only get a lot of 
horizontal lines with the sync way off.

The SyncOK led on the JPAC goes from on to off and that's that. Jumpers on 15 
and 31kHz are shorted, but I don't think this is JPAC related.

I have other decent screens up to 768x288, but this particular resolution 
fails.

HW setup:
Hantarex polo, linux SVGALIB slang, GF2mx, JPAC

device_video_format 15750 0.740741 0.0740741 0.0740741 0.111111 0.916031 
0.0114504 0.0114504 0.0610687
device_video_pclock 5-90
device_video_hclock 15.75
device_video_vclock 45-65

Any tips or leads?

regards,
Martijn
