I have them, just not physical versions. I bought the digital pack. This is why I was having issues using Acatool before as I had to take out my CF card to install new OS on blank card and it was just a nightmare. Workaround was to use HstWB image for 3.1.4 install which have a rom switcher function built. Not quite sure how it works but it is able to find rom for 3.1.4 on your HD and this is placed there during installation from the image. It's all a little confusing actually but I have made OS 3.1.4 installs a few times now spliced with Classic WB full and it's great.
However as I have the rom files, a friend of mine is actually going to burn me chips as well. He's just waiting on blank roms.
