WinUAE Workbench Display Issue

[Managarm]

Hi Guys,

I hope someone can help. I'm using WinUAE to emulate an A1200 running Workbench 3.9. I swear I didn't change anything, but one day I loaded it up and the resolution had gone from 1024 X 768 Picasso to 320 X 200 PAL. When I tried to change it, the screen's so small the Save and Use buttons aren't visible!

Then, because I'm an idiot, I decided to mess with the Overscan preferences to see if I could scroll down to it. Instead, I'm left with being able to move the mouse around a small portion of the top left of the screen.

Is there any way out of this without a reinstall?

Thanks for the reply; I've had some joy. Trying to launch Workbench off a floppy and running the Screenmodes prefs does nothing. Literally. It just flashes the "Attempting to load..." message then nothing.

I renamed the Screenmodes and Overscan prefs files and the screen area is now the normal size. It's still stuck on the tiny resolution however and I can't see the Use or Save buttons.

Is there anyway of editing the .prefs file manually? I know it's not a text file, it appears to be some sort of IFF?
