Title: Mouse pointer glitch after 3.1
Post by: dougal on February 24, 2012, 10:48:13 AM

I installed a 3.1 rom on my A2000 which worked fine in an A500 and an A600.

Now the mouse pointer is all glitchy. I tried booting from the original wb floppies aswel but same.

Pic attached

Weird!! I replaced the OCS Agnus to a spare ECS one i have and now the pointer is good but the Amiga is in NTSC :S

Dammit!! What is wrong here

Did u accidently use an NTSC Agnus? (Part number: 318070-01) (or possibly part number: 318069-17)

The A2000's original agnus seems to have buggered up and no longer works. I am stuck with this NTSC one now.

I can boot into PAL by selecting it from early startup but is there an easier more permanent way?

You probably need to change J102
