I'd like this post to be a way to highlight, with everybody's suggestions, which are the games that work well on the 770, loading them from the xmaeme gui, without using additional hardware (gamepad).

I mean, those that are worth having on the mmc to browse for (provided we own the licence for them, of course) and play. Those playable, smoothly playable. Those for which you have not to blame the lack of another key. Those you load and say "hey, didn't think to this game, it really fits rather well on this device...".

I'll start with mine (name of game, name of rom file, versions used for test):

* pacman, pacman, xmame 0.58.1-3, xmaeme 0.3

Thanks for other suggestions, if any!
