Doesn't feel like a bubble decreases lag, more that it reduces input delay which can make games feel laggy. All of these games are 30fps, the only one I played here was Tenkaichi Tag Team. Ran just like it does on real hardware.
framerate lag? definitely in some games and areas. You have to remember the vita isn't emulating these games it's using actual psp hardware so if a game lags on psp it will lag on this. overclocking the internal psp helps, tell me what the game is.
Best process to get all my hacks and games over? I understand some homebrew may be incompatible but main thing I don't want to lose is years of miis in my plaza + activity log + save data. Could I just first clone all the 3DS SD files to a larger one (micro) would that work with just one SD?
