I added some binary code into the text of one of my commands and it ended up breaking the game.

I can't open the game, edit it, play it, etc.

Is there any possible way to view the source and delete that specific command? Would anyone be able to clear it for me?

You can just edit the ASLX file in a regular text editor and remove the problem code. The ALSX file is basically just an XML file so you don't need any special programs to edit it. Just to run it and/or compile it.

As greig said open your game with a texteditor, search for [78, 80] and delete the brackets. Don't use [ or ] in your game

Thanks, this did help. This means it wasn't the binary I had put in the game, it was the special characters in a different part of the game.

It's worth mentioning that Quest 5.2 is a bit more forgiving of this kind of error - your game will still be openable in the Editor even if it contains a template error.
