i'm not really into the games but android hax are pretty easy because the back-end is all linux. there's a neat app for the PC called ADB which stands for Android Debug Bridge, basically you just connect your droid device via USB to the PC then put the device into debug/developer mode and run ADB to get remote terminal and access the filesystem. A lot of the "hack" apps are really just shell scripts and linux tweaks with a flashy ad-filled front-end. Also, Opera Mobile is the best Android browser so far.
