I am pretty sure that the Joe Zambuto program would have been affected as I think this program parsed the charts to create track models and pars. I am not sure that the program can do it now without manual entry or maybe chart files that include running times and positional information.
Also Equisim used to store (but not parse) the results charts from Bris as well. I never used that feature so I am assuming that it doesn't work now either.
Yes, EquiSim's chart viewer functionality relied on the HTML based files. Hosed by the switch. There is a new feature to use the comprehensive chart files, but those aren't free....
