Ah, I used 3.6.1 for the web build features but I didn't realise ScummVM doesn't support it yet. I tested adding the game, but I should have tried to run it. I blame late nights and looming competition deadlines.
Unfortunately there isn't a nice way to downgrade the game file to 3.6.0, it's too different. What are you wanting to play on? I can do a Linux or Android build but I haven't got anything set up to test them with.
