    Hi @CorpseSlayer 👋

    I put together a patch for this. I wasn't able to test it myself since I don't have an external drive handy, but the fix is straightforward:

    Root cause: cmd.exe on Windows interprets forward slashes (/) as command-line option separators, not path separators. When the emulator is on G:/Emulators/KytyPlus-v1.7/, cmd.exe was trying to run G: (drive change) then /Emulators/KytyPlus-v1.7 as a command — hence the error 'G:/Emulators/KytyPlus-v1.7' is not recognized.

    Fix in mainDialog.cpp (line 361-375):

    • QDir::toNativeSeparators() — converts G:/Emulators/... to G:\Emulators\...
    • Auto-quoting — wraps the path in quotes if it contains spaces, parentheses, ^, or &
    • This ensures cmd.exe treats the entire path as a single executable argument rather than splitting on /

    If you're able to test it with your external drive, let me know if it works.

    @CorpseSlayer v1.8 is up now with the fix. You can grab the ZIP from the Releases page or build from source if you prefer. Let me know if it sorts out the external drive issue.

    Thank i will tested,

    I took a Video of the testing..
    https://streamable.com/7ryvh1

    I am not sure why the launcher.exe is not working but if you load the
    game by using cmd and the commands to load the game it works fine.
    please notice that i had to upload the video to this website so you can
    see the error because directly from git is impossible to uploaded.

    Hey @CorpseSlayer, quick question — would you mind if I used your testing video on the project README, website, or for press purposes? I'll credit you as the tester. No worries if not.
