I installed specified files to the root of sdcard. I also update the firmware with most recent one you provided. I renamed newcpu.rbf to core.rbf. Although this updating process ended without problem but after i got "out of range" error from my lcd. The boot screen, rolling amiga ball with some text can be seen when mist switched on.
I have been using this monitor with beta aga core without any problem.
So what is the issue? Have you got any idea?
