Retina-izer tweak on JB iPhone4 playing Sonic!
I made this video to show off the new tweak retina-izer that was just released on Cydia. What it does is that it will play select games (updates will increase supported games) at full resolution giving you the full retina experience. I made a video showing the difference with and without retina-izer installed. Take a look, the difference is a bit subtle at first glance but you can definitely see the increased resolution as Sonic is smaller and sharper with Retina-izer...
Excuse the stuttering, it was caused by playing Sonic and running Display Recorder at the same time. Normally there is zero stuttering...
Retinaizer forces native resolution (960x640) rendering in OpenGLES apps on the iPhone4 and IpodTouch4G
Retina-izer is free on Cydia.
Here are two Screen grabs:
