I have been writing down all the games that run at constant 60/60 with every arcade emulator for the GCW Zero. The list is not to difficult to manage, considering I have reduced my selection to games at native res without stretch, that is, games at 320x240, 320x224, 288x224 at the most (eg. Sunset Riders), and also resolutions which more or less keep the aspect ratio when the borders are not too large. I exclude all vertical games and all games that do not fit in 320x240 because their horizontal or vertical resolutions are higher (eg. CPS2). Of course, we don't have to mention Neogeo games. I have tested all my favourite games that meet this requirements with FBA, MAME4ALL and, not so with not so thoroughly, with some versions of XMAME. The idea is to find games that run perfectly, at least in terms of performance, and look great without any stretch, indicating in which of the emulators this happens.
