sd games will not play on vega

[Guest redroadster]

Hi, I have some games on sd card - if i install them on my rooted commtiva n700 they load and play no problem they also work on a samsung tab.. however if i try to load them on my vega they will not play - i can load and see the game icon on screen but when i press icon just get blank screen for a few seconds and then back the home screen... any one got any ideas why they will not play on the vega.... thanks in advance...
