I look at OutRun in MAME, then compare it to the (rather basic) DOS/Tandy versions, along with the ports in Shenmue 2 and Yakuza 0/6/7/Judgment. Plus the re-engineered Cannonball project for fun.
It's interesting to see how inaccurate the Shenmue 2 version was, plus how almost all Yakuza ports are missing a fair bit of the screen picture!
If you like that I'm gradually covering the (over 60 I believe) arcade-to-PC Sega ports, the playlist is here:
