I believe the Saturn and PC games should be separate or split somehow from the arcade and PS2 version as they're conversions, not ports. Just like Daytona USA.
I think it's amazing that PAL is combined with NTSC. Racing games are easier to play in 50 Hz. Also amazing that emulators are combined with real console. Even more amazing that all platforms are combined. There needs to be a split of some sort.
Yeah, it's quite a mess. You also reminded me of something that might be of note to some players.
The Model 2 emulator isn't perfect and other players will explain this better but the rival cars are buggy or lag behind and are not exactly where they should be. For example, it's not possible to bounce from a green rival car on the final curve of the Desert track in Championship mode because the car isn't in position. So emulator players might be at a disadvantage throughout their runs though skilled players can still achieve really fast times.
Emulator and Arcade shouldn't even be combined, never mind Saturn. Come on mods, sort it out please..
