I also didn't do the rotated walking sprites for the loops, because Aburtos skipped doing those as well. Even drew in the rain particles for the rings in Sky High Zone Act 2! I also had to change the use of the sign graphics the un-spun sign had tiles that were shared with the ring sign, so I made a ? sign for un-spun version and kept things a bit more like they were in the original game. So I put as many of them into Sonic 2 SMS as I possibly could! I didn't bother with any compressed graphics because but I did take the time to make all the stage ring graphics properly set up. So this dude on the deviantArts took one of my sprite rips from long ago and made some really good refreshed sprites. Lemme throw something together to clear out the bad mojo. Kinda like how it normally looks on a PAL system/TV. I believe you'd also see a Mega Drive drawing all the 240 lines, but it only draws a single color on the other lines besides the main 224. If you manually decrease the width on a NTSC TV, you'd see the overscanned lines without any problem back when 4:3 TV broadcasts were a thing. But since only 224 lines would be visible on most TVs, most video games consoles up to the 2000s only had an active video resolution of 224/448 lines because anything more would be a waste of resources. To prevent you from seeing the end of the picture if the height temporarily decreased slightly, TV manufactures calibrated the sets so only around 448 lines were seen onscreen, while the rest is drawn outside of the CRT's visible area (overscan).Ĭonsole manufacturers used a technique that, to simplify, turned the 480 lines at 60 half frames per second video signal into 240 lines at 60 full frames per second. Depending on power fluctuations, those scanlines could be drawn further or closer apart from each other, resulting in increased or decreased vertical picture size. What happens is that analog TVs don't have pixels, they just draw scanlines from left to right at whichever point on the screen they want to, basically (contrary to popular belief, scanlines are the drawn lines, not the black lines inbetween). Some of those are used for blanking and whatelse, but there's still 480 lines left for video. NTSC signals (and PAL-M, for that matter) are made up of 525 interlaced lines.
