Thanks, DrBollox! Your script works perfectly for me.
Like you, I haven't figured out how to make it launch in full screen. I couldn't find any command in your script for that, nor any shortcut to switch the window to full screen (maybe an idea for your AutoHotkey script?).
There's another problem I haven't found a solution for: changing the game’s key mappings to use an X-Arcade. I tried with AutoHotkey, but without success.
