Just turned out that AMW’s and especially Cougar’s parameters are wrong (ie they differ from the dreamcast version). Nero found this out by browsing through the Dreamcast version’s CARINFO.TXT. The Dreamcast parameters are to be considered as the correct ones as they are more recent.
What now? You can fix them by replacing the lines after the break of your AMW’s and Cougar’s Parameters.txt (from ‘Handling Related Stuff’ onwards) or downloading both fixed Parameters.txt i fixed for you.
