GRAND PRIX 2021 standalone mod

For people who don't want to use CSM, i compiled a standalone mod. It comes with an installer and a GUI which makes it very easy to play and customize the mod:


Just make sure you have Net6.0 installed (it's usually installed if you have a newer computer). If this message pop's up, just download net6.0 (desktop version) and install it:


It containes almost all features the CSM mod does, except for all the track-specific liveries (cars, helmets, marshalls, etc.). I have added 5 track specific cars.wad (default, Monaco, Zandvoort & Monza, Istanbul, Yas) which will automatically be loaded if you select the respective track in GP4.
Also in the GUI you can select if you want to run rounds 1-17 or 18-22.

Please note: There are no tracks included in this mod. But it's very simple to add your custom tracks, just follow the instructions in the GUI (hover over the buttons and read the tools tips).
