I've made an issue on the Yabause Git about the blue screen to see if anyone has any ideas.

Here's a new Video showing a handful of games running with latest changes on the new PS1 Core :)...
btw @BigOnYa the health bar doesnt decrease when i take damage (and yes i put the "at the beggining of the scene change value of greenflatbar: set to Protagonistcopmode.Health::Health())
@Xdqwerty there is health behaviour you can add to your character, then to use a health bar is lil more complicated, google n watch a few tutorial video on it, be too hard to explain here.
I know you have to create a health and health max variable. Then there is a calculation you use in code to subtract width size of the health bar. Google few vids.
