Tested: GREAT! Now with the tab key mapped the rotation is no more a problem, and freedom of keymapping is wonderful. The possibility to map tapping is worth alone the upgrade, it's like having another free button, and much more comfortable!

I'd like to write two requests, but if Tak or anyone else wants not to take the pain of implementing them, I want to say it's just good as is: just consider them as suggestions please.

So here they are: it would be better to map the exit key (home) to the zoom-out button, or the on/off button if possible: it's a pity the home key cannot be used for playing, it's on the front side and comfortable, distant enough from the pad.
And the other suggestion: it would be nice in xmaeme an input field (along with the existing select field) where a game name can be directly written: if something is written, xmaeme uses that string to load the corresponding game, instead of the select-field's selection. And useful if its content is remembered on exit, too.
