I can’t get this to work on the real hardware. In reality boy, it works but only without the asm line, but on hw it doesn’t work either with or without it. I am using the new crt0 and my code looks like in jorgeche’s post.
I was messing with the BRT registers between the screen updates to make it use 3 different red shades for every odd frame. I’ll look at it again when I get my flashboy 😉
I found out that the screens on a faulty vb works perfectly if you just make sure that the room you’re playing in is pitch black, so no outside light reaches the screens.
And about those game bits that are too thick to fit the vb’s deep holes, I filed the sides down on one of those so now it fits perfectly.
