Here's a reformatted version for all you non-vi dudes:
Hiya, you guys post like crazy.. hard to keep up with you :)
Here are some answers to some of your questions:
- The Hotsync program on the emulated Palm will use the serial port on the ipaq to connect to the Palm Desktop suite on the PC or Mac.
- The reason I didn't use the POSE or Copilot source codes is that, first: POSE is extremely slow. POSE is mainly intended to be used as a programmers debugging tool and not being a speed daemon. There is all kind of real slowniness inthere like statistics, real time debugging, fault tolerance code and profiling code. Plus it's VERY VERY VERY object oriented and that C++ overhead really makes the emulator just crawl. I really must give the programmers an eloge for keeping the source code clean, though. The Copilot source code, is the ancestor of POSE, although written in C with a slash ofC++ inthere, it's very limited. The greatest decision factor was that both used the UAE source code by Berndt Schmidt, which is itself a generic 680x0 emulator but still SLOW on the ARM. Copilot uses 0.69 and POSE uses the latest, I believe, 0.8.15 (please correct me if I'm wrong).
- The reason to why I chose this approach of emulating the hardware instead of emulating the trap calls by themselves is that first, it's much easier to emulate the hardware than to write 1000+ APIS correctly. Second, that would've gotten myself in more copyright trouble that I would've wanted with Palm. Ofcourse the ROM approach can still get me in trouble, but this is more or less be debatable.
- About the Linux DA running on the Palm emulator. The good part is: YES, it is possible. Since my emulator emulates the hardware itself, bit by bit without ANY knowledge to the Palm Os whatsoever, all I have to do is add support for Linux DA ROM loading and if the LinuxDA ROMs are correct, then it should work.
Any more questions please redirect them either here or to info@kodeness.com
