I'm guessing you changed pbBGMPlay(data_system.title_bgm) to pbBGMPlay(Title_Oringin)? You need quotes around the filename - pbBGMPlay("Title_Oringin"). (data_system.title_bgm is a variable, not a string, so that's why it can be put in without them)

But there's not really any reason why you'd need to edit the scripts to do this - the game just looks for any BGM file named "Title", so rather than edit the script, you could just rename your file Title and leave the script as it is.

Are you particularly far in development? Because v17 is pretty old, I'd strongly recommend working with the latest version of Essentials instead.

Also, the PrtScn key takes a screencap, it's easier to share and look at than a photo of a monitor.

You’ll likely need to upgrade through each vers, though- so go from v17 to v18, then to v19, then to v20. (you can find downloads for them all on Luka’s website)

Maruno’s also mentioned that it’s sometimes easier to skip porting old PBS files and just make your changes in the latest ones, since there’s some flags and stuff that were added in later versions.

Look at events in the default maps, there’s lots of examples of using self switches for this. (the choosing starter cutscene and Poke Balls in the lab, the overworld Mew and Deoxys, the item balls on Route 2…)
