Ran into this weird problem... I have a MSX2+ modded NMS8235 (vdp + bios has been changed) and a Sony BVM20F1E crt connected via rgb scart. When I run e.g. Gryzor with Megaflash SCC+ SD, the Konami logo screen is clearly out of sync. Then when the game enters the actual menus etc. all is fine and looking really, really good. Same happens with e.g. Pengo, the Paxanga logo goes all overt the place, but then all is ok.
I have tested with both RGBs and RGB as both a re available as separate inputs on the Sony. Same result.
Can someone explain what's happening? Is there a screen mode tester somewhere available
