"Jumpy" video on a CRT (Philips CM8833-2) with SOME cores only.

Unread post by reno »

Hi,

The SCART output of my MiSTer Multisystem is connected to a Philips CM8833-2 CRT monitor (15KHz, similar to Commodore 1084S) using a SCART to RGB DB9 adapter.

It works perfectly with most cores, but for several of them the picture "jumps" vertically by a few lines, around 5-10 times per second. It's very annoying.

Switching between PAL / NTSC doesn't make a difference.
Any ideas what I should look at ?

Some cores with the problem :

Atari ST
Amiga
Atari 7800
N64
Saturn

Some cores working fine :

SNES
Megadrive
NES
Game Gear
Game Boy / GBA
PC Engine
Amstrad CPC
ZX Spectrum
Commodore 64
Colecovision
R-Type (world) - Arcade
