@Grila, Well way to make me look like a total dumbass!! You are of course absolutely right, I have my main system at 100% and never even gave it a thought on my tablet. Just switched too 100% and it fits perfectly, so chalk that one up to me being dumb, apologies. I did however try that other view just before you posted and that seem to work great at 125% so may stick to that for usability's sake on a screen that size. Thanks again for all your hard work.
@Porl Hendy Its pretty good with this theme, it can struggle quite badly with other themes, but this theme is both beautiful and lightweight so not to bad at all, although I don't have many systems imported. As for emulation pretty much anything I have in retroarch has worked pretty well, even N64 if you keep it at native res some games you can even bump up to 720p. The only issue I had was ps1 in retroarch, it wasn't good at all, but I put pcsxr on it and that was much better. Don't have the space for ps1 games on the tablet though so I deleted all that and just concentrated on 8 and 16bit stuff which as I said works great.
