The man who brought the homebrew scene the Interop Unlock method has now created an extensive guide for developers to make use of that loophole. Heathcliff74 has posted to XDA-Developers a step-by-step tutorial for developers living on the opposite side of the fence to enable their homebrew apps with native code. Actually the tutorial has been available for a while now, but there's a pretty good reason we're talking about it now. Namely it's due to Jerry Jiang's Screen Capturer which obviously makes use of native code and more importantly shows the potential of what homebrew apps could be capable of with Mango's new APIs. So if you have some in-between time this week and want to push your app to its limits, make sure you read through the whole tutorial.
