Hi BIGBEN,
I'm glad to hear that you're doing well.
All of my Palm games use the PalmOS APIs and custom routines that I've written. They don't use PF/PHAL because (as of yet) it doesn't exist for Palm OS. But, I am anxiously waiting for the Palm PF/PHAL release.
I have ported 2 of my Palm games to Pocket PC. Both of these games use PF/PHAL.
