How to specify custom default conf filename in Windows build?

[emendelson]

The answer to this should be obvious, but I can't find it in the code. I want to make a custom build of DOSBox-X for Windows that will use a different default conf file from the conf file used by the custom build. I want to do this so that I can distribute a copy of DOSBox-X with custom settings built in by being specified in sdlmain.cpp and other files, and I want to make sure that this custom build won't pick up the default settings from a different copy.

Is this possible? Again - I'm trying to do this without expecting the user to specify a conf file in the command-line. I'm trying to do this so that the default conf filename is built into the app itself.

Many thanks for any help.

Config::ParseConfigFile in setup.cpp may be the first place you should look into.

@maron2000 - Thank you! I've looked there and in sdlmain.cpp, but I can't find anyplace where this kind of default filename gets constructed:

C:\Users\<USERNAME>\AppData\Local\DOSBox-X\dosbox-x-2025.02.01.conf

Probably it's staring me in the face, but I've managed to miss it....

Cross::GetPlatformConfigDir in cross.cpp seems to be the answer.
