Gawain, my advice to you is to get GemRB. It's a free application which will let you play the IE based games on Android and iPad. I swear by it - I gave Planescape: Torment on my HTC One at all times. I don't think you can do better than that.
This will allow you to grab a currently installed version of your game, so BG with TuTu, BG2 with UB, PS:T with Quinn's Restoration pack, Fallout 2 with Resotration Mod, etc.
