Yes, although there are one or two functions that have been declared obsolete and are not supported, but you're really unlikely to be using these, since they're pretty obscure. > I think I could try to use the uploader for the rom of my device to > transfer the rom to the pc and then try it in the Palm Emulator... The ROM on an ARM device contains ARM code. The ARM-based Palm handhelds do not emulate 68k hardware and run a 68k ROM; instead, they have a bunch of ARM code, which emulates a 68k environment for APPLICATIONS ONLY. When an application makes a system call like, say, MemSet(), the 68k code makes the call, but once the system receives it, it runs MemSet() as native ARM code. The old Emulator takes 68k ROM files, so it will not understand the ARM code in the ARM device's ROM. The Simulator is actually basically a Windows applicatin built from (mostly) the same code that was used to build the ARM code for the device. The Simulator doesn't contain or emulate ARM code. However, (on Windows) the Simulator uses the same mechanism that the ARM code uses (on the actual Palm) to emulate 68k instructions, so they both can run 68k applications. - Logan -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
