Help with LUA scripting.

[MastaG]

Hi threre gang,

I'd like to offer my Dreamcast for helping out with some automated test cases.
For that I'd like DreamShell to download an iso file from a plain http server and run it at startup instead of showing the main menu.

So I'm trying to edit the DS/lua/startup.lua file:

-- Internal DreamShell lua functions:
--
--    OpenModule             Open module file and return ID
--    CloseModule            Close module by ID
--    GetModuleByName        Get module ID by module NAME
--
--    AddApp                 Add app by XML file, return app NAME
--    OpenApp                Open app by NAME (second argument for args)
--    CloseApp               Close app by NAME (second argument for change unload flag)
--
--    ShowConsole
--    HideConsole
--    SetDebugIO             Set the debug output (scif, dclsocket, fb, ds, sd). By default is ds.
--    Sleep                  Sleep in current thread (in ms)
--    MapleAttached          Check for attached maple device
--
--    Bit library:           bit.or, bit.and, bit.not, bit.xor
--    File system library:   lfs.chdir, lfs.currentdir, lfs.dir, lfs.mkdir, lfs.rmdir

            end

        return true;

};

if not DreamShell.initialized then
    DreamShell:Initialize();
end

As you can see I didn't got very far.

Any help would be greatly appreciated.
