WB3.1 on 3.0 roms?

[vic20owner]

I just noticed that my Amiga came with what I think was WB3.1 installed. When I installed my new Hard drive, I installed WB3.0 and am now missing some features... such as the ability to move the screen position in the perferences->overscan, etc.  I *think* these are 3.1 features.

So my question is, if I dig out my Wb3.1 disks and install it on my A1200 with 3.0 roms, will it be stable or are there certain utils which will cause it to fall into a screaming guru mutilation?

thanks

WB 3.1 will run on 3.0 ROMS but some stuff refuses to run. I've actually run it on  a 600 with 2.05 ROMs before now (had to install it handraulically ) but on 2.05 ROMs you can't format and non of the Prefs work. On a 3.0 machine it should do most stuff but again there are bits that won;t open and functins that don't work.

*HOWEVER* it's a violation of the Workbench 3.1 License, technically, to run it on non 3.1 ROMs as I recall. :rtfm:

Oh and for the information of those about to send the AmigaPolice round to my house I have since installed 3.1 ROMs in both the machines mentioned above. The trouble is I only have disks for WB 2.05, WB 3.1 and OS 3.9, so I don't have any 3.0 disks to test stuff with I was only using 3.1 for hardware validation purposes - as soon as the computers were known good they got 3.1 ROMs slammed in them.

You're wrong about that. Workbench 3.1 was sold with or without ROMs. The very first Workbench 3.1 review that I read said that the reviewer bought the Workbench-only 3.1 and he was using it with 3.0 ROMs.

I've been using WB 3.1 with 3.0 ROMs for years and only ever had one single piece of software not run because it required 3.1 ROMs. (Matrix screensaver, needed some graphics routine in 3.1)
