I took a screenshot from the dither.gen ROM to show how the effect looks like without a filter. If anyone else is going to use the ROM then do the level select code to get to Labyrinth Zone quicker. Once in the zone press start to make the water appear. To raise or lower the water level press up or down respectively. Here’s a larger sized version of the image in case anyone wants a better look at it: https://archive.ph/bm7Gi/d8443fbb16b07b3f427ec56d9c5fe3cf5a48d452.png The information originally came from Yasushi Yamaguchi (Judy Totoya) in a 2018 fan published magazine titled “ファンタシースター 〜31年目の原点〜 ” which translated is “Phantasy Star ~The Origin of the 31st Year~” A thread by @Gryson shares this information here: https://forums.sonicretro.org/index.php?threads/origins-of-the-sonic-1-water-effect-revealed.40037/ I found a PDF sample of the magazine containing some pages but unfortunately it doesn’t include the section where the water effect is mentioned. http://www.space-harrier.com/ps/samp.pdf The sample does include a page where there’s an image of Naoto Ohshima, Yamaguchi, and Izuho Numata (Ippo) so it is useful in seeing that at least. As a bonus here’s some signatures all three did for the interviewer including character sketches which I think look nice. https://archive.vn/YYa6b/5dbdc79dbca24a6a6e19543ea82bb3acbef18368.jpg Source: https://twitter.com/Va_HARA/status/1367133793673388034 https://archive.vn/YYa6b I remember a thread you made asking if there was any information about how developers would consciously make sprites in a certain way in order for them to be properly displayed through composite video and @Gryson provided translated information sourced from that same Phantasy Star fan published magazine interview in regards to that. https://forums.sonicretro.org/index.php?threads/sega-genesis-and-composite-video.40262/#post-983262
