Hi,
There once be a similar patch(
http://code.google.com/p/patch-hosting-for-android-x86-support/downloads/detail?name=32bpp.patch)
but
not for Android 2.1.
Android 2.1 has changed much so i rewrote a patch to make Android Support
32bpp mode.
If you want to use default 16bpp, redefine the HAVE_ANDROID_32BPP 0.
