I was covinced it was a setting change I'd done but didn't know which!
spent hours trying different combinations because I knew that i had it running in the past, but state refused to load despite every settings combination i'd tried, CPU, sound, Blitt, Ram ect.
I'd almost given up because it would power off psp totally upon loading, so it took ages to keep tying new configs. I thought as a last resort, I'd change how it looked.
settings were:
Zoom: No Zoom
aspect ratio: 16:9
autozoom: on < this is what causes lockup on ADF and savestate loading >
screen lock: on
If you want to try it: 0.63 CE settings are (not tried on 0.71 yet)
CPU:68000
CPU speed: chipset
CPU Chipset ratio 61%
immediate blits : on
chipset: OCS
sound: stereo
chipmem: 512kb
Bogomem: 512kb
Kickstart: 1.3
Frameskip: 3
zoom: 25%
Aspect ratio: 25%
Auto Zoom: off
Screen Lock: on
The game will load ok then but you will have an off centered view.
so set to Auto Zoom: on ( this corrects view to centre)
once centred, go back to
Auto zoom: off
then you can play game with centred view, without lockups.
All very strange, I know but Its what i found to be true.
If you dont believe me try loading menace adf with Autozoom: on
I'll bet pound to a penny it powers off your psp! lol
