No.23282 Robbbert Moderator 18 days ago	Confirmed. Also, the lakes are blue in the video, but purple in MAME.
No.23283 hap Developer 18 days ago	Titlescreen background color is fixed here: https://github.com/mamedev/mame/commit/dabc8a9707d266046abd9401a638841af7d18849 I also corrected reading from paletteram, but I don't think the games ever read paletteram. Schematics are hard to read, from there it doesn't look like there's any difference between the B color output and G/R.

No.23285 hap Developer 18 days ago	Yeah, I don't know why the blue is stronger on the PCB video. Like I said, I see no difference between r/g/b outputs in the schematics.
