I don't think it was the case with that game because this only happens if I set a value from +11 to go up in Y-Pos, with the same resolution set (NTSC) and Y-Pos 10 or lower the initial intro image is not pixelated. The resolution I selected was NTSC, not the one with the wording "interlaced". If I set NTSC interlaced the screen is cut to 90%, what I see is only a small part of a zoomed image. If I set NTSC and enable the Emulate Field Flipping function the image is no longer pixelated but maintains a flashing flicker during the intro. Another curious fact is that I also tried with Opl 1.2 beta 2014, the exact same thing happens if a value greater than 10 is set in Y-Pos but compared to Opl 1.0.0 the pixellated image changes based on the scene shown, being the dynamic effect, for example the exact scene of the pixelated image that I loaded, with the GSM of the OPL 1.2 beta is not displayed pixelated but the scene after it is displayed pixelated.We do what we can.
Remember that games like 2D (cinematic) animations should always be set to "interlaced" never as "progressive" that's why I was asking about the resolutions you used.
because if you try to use progressive scan in a 2d game the results are "pixelation" just like the image you show.
The interlaced lines "soften" 2D games a little, keep that in mind.
