I got P41CX to support more ROMs ! Message #1 Posted by Vincent Weber on 18 Apr 2006, 7:21 p.m.
Hi all,
Since Charles Lee does not seem to develop P41CX (the HP-41CX emulator for Palmos) anymore, and not being able to add your own ROMs besides those provided is frustrating, I hacked the Rom manager of P41CX with a Hex editor, and I managed to get it to support the following modules, on top of the ROMs already included:
- AEC ROM,
- CCD was replaced by CCD PLUS from Angel Martin, so that there is no conflict with the Advantage module,
- CCD OS/X is also provided as an alternative,
- Sandmath/41Z/Toolbox/Alpha Roms from Angel Martin; I did not include Sandmath 3D support, since unfortunately P41CX does not support lowercase characters, used by Sandbox menu. Alsos, these 4 Roms provide additional functionality to the Sandbox; they also use more ports, but since P41CX allows you to hot swap modules with different memory banks, this is no big deal (you are unlikely to need of 4 of them within the same program...),
- David Assembler + Labels.
To do this, since the module list if harcoded, I had to remove the Structure module (a 2-page one which I don't use) and the Math module (which is pretty useless when you have the Advantage + Sandmath). To still use the missing modules, I created another instance of the ROM manager with a different name. Not very pretty, but no much choice...
I believe that anyway this is the best set of ROMs one can dream of; I would also like the HEPAX of course, but P41CX does not support it.
If you are interested with the hacked version, just email me and I will provide it to you. I may also be able to include your favourite ROM (at the expense of another ROM) if it is not already there.
Regards,
Vincent
