how about putting it in the .prc compressed and you extract into a .pdb or onto the VFS card upon installation; based on a user option? you can detect if VFS is present, and, ask - and, if it isn't, just create the file stream (dont need hostcontrol then) for what it is worth, using VFS direct and palm filestream databases renders little different in performance in regards to accessing the data stored within a file :) we did a number of tests, accessing a .mpg file on a sony clie for playback with both techniques.. maybe 2-3% difference (faster in ram) how big is this .gam file? is it feasible to have an installer which generates it as appropriate? --- Aaron Ardiri [EMAIL PROTECTED] CEO - CTO +46 70 656 1143 Mobile Wizardry http://www.mobilewizardry.com/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
