I don't remember much of Daytona USA 2 on the arcades as I only played a few times before it was retired. But the way the CPU cars behave in the supermodel emulator compared to the official ports inside the Yakuza games is very different. I noticed that the CPU in supermodel race almost on rails, but in the official port they try to block you, they change lines all the time, they ram the back of your car... I noticed that supermodel does not do any of that, and that only shows how some emulators are very inacurate. I was trying to do a run on supermodel and got very disapointed. I vaguely remember the real arcade being very much like the official port and much less like the supermodel emulator.

I even watched some of the runs here and they are very much not like the real hardware at all. I thought I was imagining things, but I saw a run on youtube with the real arcade, and that oppened my eyes to how inacurate supermodel is.

Well, at least supermodel suports wheels very well and has widescreen support.

See here how the real arcade was and compare:
