Ossc 1.7 and wierd issue with Dreamcast

[rusekchwdp]

Hi.I bought ossc back in January but didnt have time to play around with it.

Im using it with my Dreamcast and RGC component cable with 31khz switch.

Im using Wobbling Pixel settings for VGA and all is fine up unitl 30min of gameplay when screen goes black for a 2-3 seconds but ossc doesnt loose sync-light stays green.

My settings are

Dtv480P

Allow upsamplex 2x on.

When I switch cable  scart its fine for hours but quality isnt great.

Any help would be greatly appreciated

Consistently after 30 mins or around 30 minute mark? Always at the same point in your game or not?

Around 30min of gameplay.Could be any game and any stage.I tried Soul Calibur patched and stock,Headhunter Pal vga forced and Crazy Taxi.Once 30min is passed since OSSC started I can switch games but problem persist even in GDEmu menu screen goes black for 2-3s

Edit:I have to power off OSSC for 5min and then everything is back to normal for another 30min .

I found old thread with similar issue but with vga.

I tried newest firmware,4 hdmi cables .

No diferrence on 480P. Still goes black after 30min.

Any idea?

I had similar issue with one DIY board which had cold solder joint on FPGA bottom GND pad. If the same also happens with another source/input, then it’s probably best to RMA the board.
