I edited the MKDX server exe file on each cab to use custom profile names so i didn't have to type them in. Using a hex editor like HxD you can search for strings of hex values. Pseudo!! is 50 73 65 75 64 6f 21 21, but it turns out to be broken up by zeroes, so you're looking for 50 00 73 00 65 00 75 00 64 00 6f 00 21 00 21 (if i've typed that right). Using any Text to Hex converter online you can change that to what you want, keeping the zeroes for spacing.
May i ask how you're launching and closing games on your setup, in particular MKDX? I can't get autohotkey to close the game, i have to manually hit esc on the wireless keyboard i have connected. It's the only game i've ever hat trouble scripting for complete operation through my attractmode frontend.
Using an AHK script and batfiles, i can open the server and open the game. I then have joy-to-key set up to deliver a hotkey that should make the script close the game and return to the frontend. This works for every other game, with a couple of tweaks depending, but with MKDX i have to manually hit esc, and when at the desktop i can still see the scrip running in the background, which then works normally with the hotkey, and opens the frontend again.
Does Teknoparrot have the ability to rebind the exit key now, and i missed it?
