1) What do you mean you can’t save the config?

2) I have the latest model with 512 onboard. Perhaps you have an earlier model? Either way, 256 works fine. I have heard 128 does too, and some have said it is the optimal setting, but I can’t tell the difference tbh.

3) I use a Windows desktop as well and SSH into my Pi using Putty. Pasting in a Putty window is a simple right-click of the mouse. Just make sure your enter insert mode in vi before you paste! If you don’t know vi well, use nano. It makes more sense to most.

5) Oh cool. I’ll have to check that out. I’ve noticed that pisnes saves games at ~/.snessavegames (or something like that in the home folder). I copied that to my new build when I went from 1.x to 2.2 and my games restored fine.
