Giant cursors vs. screen border -- quick test!

Post by scarybeasts » Wed Aug 28, 2019 6:38 am

Hi,

There's an interesting question of what happens when a cursor starts within the screen border but then keeps going! There's general emulator agreement that the cursor spews outside of the CRTC render area (perhaps because the ULA is mixing it in). But it'd be good to quickly check on a real beeb.

This will need an OS1.2 model B because of the hard coded location needed to hack the ULA control copy:

MODE 0
?&248=&FC

Congrats, now you have a superlong cursor!

If you type a bunch of A's, does the cursor stick out past the border as in this attached screenshot (from jsbeeb) or not?
