Bug fix!
I've been fighting some issues with compilation as I'm still figuring out how to get consistent binaries.
I've tested this release on a VM with a fresh install of Windows 11 and it works.
Usage
Generate an example config.json (or use your existing config)
archopen.exe --generate-configCustomize config.json so each extension has a core_name.dll matching a core in the cores directory of your RetroArch install.
Right click rom file, "Open With", "Choose an App on your PC", and select ArchOpen.exe
Enjoy !
