Hey, vesalia has 3.1 kickstart roms for the A600 for 17€

I think you could soft kick to 3.0 kickstart to install WB3.x with skick but then you need more memory, but imho not worth the hassle when 3.x roms are cheep.
A SRAM card 2 or 4MB do a lot on the A600 and mine could play quite a lot of whdload games with a SRAM card, removing preload made quite a few multi-floppy games work also.
But I had no use of WB3.1 on my 600 so I used classicWB GAAE and I loved it.
Do you have any reason/need to use WB3.1 over 2.x?
What do you intend to use the A600 for?
