UPDATE - see my reply for an explanation!
I'm slowly working on a comparison of Sega Arcade vs PC ports on YouTube.
My last one, about Hang-On, explained how the so-called "New Course" version in Shenmue 1+2 remaster is actually the ride-on variant from 1985, and not new at all!
I've since been looking at the other Sega super-scaler games that appear in the Yakuza/Judgment series, comparing in particular to Yakuza 6, which uses the exact same pixel scaling/aspect ratio as MAME.
In Yakuza 6 I found that both Fantasy Zone and Space Harrier are 100% pixel identical to MAME.
Out Run (apart from switched sprites) has the entire sprite layer (but not road layer) moved to the left by 1 pixel (in-game resolution).
However, Super Hang-On appears totally different in the Yakuza/Judgment series, as you can see in this comparison of the Africa stage start line:
The Africa stage in MAME then starts with: right-tightens > left > left/right/left/right...
You can see several real arcade cabinets using this ROMset - note that all are upright units: 1. https://youtu.be/wInYgON1xcU?t=18 2. hhttps://youtu.be/yo_NUdE8rFg?t=927 3. https://youtu.be/kfVSu5afkcA?t=534
Meanwhile the Africa stage in Yakuza starts with: left > left-tightens > right over hill > long left over hill...
I found a real arcade cabinet using this course, and it's a ride-on unit: https://www.youtube.com/shorts/wq8v6nbHtwU
So, in short, the Yakuza/Judgment games feature an undumped (or at least not-yet-in-MAME) version of the game!
