its set to use the home rom with vulgar speech. (H-6) I don't think you can set that off of free play I tried free play is under Adjustments, Pricing Adjustments like the 4th one in and its factory setting is no which it defaults to but is still on free play prolly being a home rom.
But if you would like to use another rom you can go into the script and find where the gamename constants are set (around line 40 or so) and put a comment (the ' key) at the start of the line that has const gname="dm_h6" and remove the ' from the line of the rom you wish to use then save the table if you wish to use that from now on.
