Which version of the multi did you test ?
Mostly RC2, now on 1.1 beta.
I can confirm at least one 1.1 beta bug reported here: the popup menu in the selector is buggy and doesn't let you change options (like switch between crt & lcd layouts). I haven't yet had a chance to confirm the other two bugs (SamSho graphics issues and Examu input intermittent issues), but it's on my list to check them. I'll try and do that tomorrow.
