EDIT: Best you can do for now is to read Soly's post below.
This launcher works by modifying the game while it's launching, you have to use the launcher every time.I'm a little confused, is this widescreen launcher still working?
I downloaded this sometime last year and never had a problem with it.
Now it seems to be reverting back to whatever resolution is set in the initial options menu.
When I first run the launcher (in 1920x1080), it creates a large window as I would expect and seems to be working. After the first run though it always reverts back to whatever resolution is set in the initial options menu.
If I delete the entire PSOBB client folder, create a new one, and run the widescreen launcher again, it will once again create a large window as expected but only on the first initial run.
Does anyone know what's going on with the launcher?
