This works! Thanks for making the IPS. Many thanks to ducon2016, HowardC and jackchen for their work on this.

Could it be that you do not have the d3dcompiler_46.dll file in the game executable's folder? Please ensure that you rename the folder "Update" to "Daytona" and that the dll isn't missing from there. Also check if your folder structure is as shown in the OP.

Awesome, thanks a lot! The game doesn't crash anymore. The only thing that's still screwed is the controls now, InpWrapper.exe in the Shell folder seems to be in charge of that. Just replace the string above in the Daytona.exe file with a hex editor and it shouldn't crash now.

You need to install DESkey DK2 drivers, you can get it at their official website.

Shell gives me "ERROR! SECURITY FAILURE 2" when I run it, also generates a bunch of logfiles into Shell folder and configs into ShellData. This is with DESkey DK2 drivers installed, it doesn't open at all without them. Game still crashes after the logos or after a few moments in attract, unfortunately. I guess it really doesn't like anything that's different from the original PC.

I have ffdshow installed, if that helps. Game loads fine in both windowed and fullscreen mode, but crashes after some time. Change ENABLE_LOG_FILE to 1 in the config.ini file in GameData to enable logging. It'll generate a logfile into the Log_DT folder in GameData. They pretty much all look like this: [2017-12-26 05:27:28.667] threadfunc_Ping begin [2017-12-26 05:27:28.667] threadfunc_Ping begin [2017-12-26 05:27:28.668] threadfunc_Ping begin [2017-12-26 05:27:28.667] threadfunc_Ping begin [2017-12-26 05:27:28.668] threadfunc_Ping begin [2017-12-26 05:27:28.668] threadfunc_Ping begin [2017-12-26 05:27:28.668] threadfunc_Ping begin [2017-12-26 05:27:30.102] Active IP list: [2017-12-26 05:27:30.102] 192.168.1.X--1 [2017-12-26 05:27:30.105] Create network group failed

This is very helpful. Thanks for your work! The game crashes around a minute after it shows the attract mode on my machine. I think the ipconfig.ini file might be what's causing it to freak out, the logfiles say something about failing to create a network group.

Can you please share how you did it? I copied the config.ini from Deploy into GameData, and Daytona.exe can go into fullscreen now, but even if I set FORCE_NET_VALID to 1 and network type to single it crashes after the "network discovery please wait" screen. I guess the game tries to find some data and fails, but I have no idea how to get it to find it. Also tried installing DESkey drivers but that does nothing except allow Shell to boot (and instantly error out) lol.
