I have Olipad 100(also HERE)Sorry to see you can play some games, probably is a android version problem, all this games are Acer iconia tab modified games, and probably need at less android 3.0.
In any case, when you get the error with that games? during instalation, download or launch?
I have tested:
9mm: black screen after sd files download
Backstab: black screen after sd files download
Let?s Golf 3: black screen after sd files download
Modern Combat 3: infinite loop loading after .APK installation (make this with all version,excuses gameloft wapstore version that says after .APK installation that my device is incompatible)
The Oregon Trail Settler:Works!
The Adventures of Tintin: black screen after sd files download
NFL Pro 2012 Free: Works!
Of others games i've working version (sometimes lg optimus 2x version,sometimes others device version)
