you may try this blit demo, it will run on VGA (640X480) mode on Pocket PC VGA edition, in the same time it can run on smartphone or normal QVGA PPC. Additional, it will load the background picture depend on the VGA or QVGA mode.
There are two problem here:
1. On VGA mode, the performance looks a little poor. (I test it on emulator). Any hint to improve the performance?
2. On VGA mode, the Stylus function seems does not work any more, I already add the HI_RES_AWARE resource item.
After I fix above problem, I will post my VGA_Fix project here.
