HP 15c CE : decoding / encoding Voyagersave files
Now that Voyagersave works with the HP 15c CE..is there a little piece of software that can turn the dump files into human readable code, and vice versa?
Thx in advance |

SwissMicos has an webpage to decode/encode dumps from their DM15L. An offline program for the HP-15C CE is my wish. https://technical.swissmicros.com/decoders/nut/ A1 HP-15C (2234A02xxx), HP-16C (2403A02xxx), HP-15C CE (9CJ323-03xxx), HP-20S (2844A16xxx), HP-12C+ (9CJ251) |

I looked around for code that translates from the raw dump file to meaningful Mnemonics and found this file : https://github.com/brouhaha/voyager-lcd/...r_code.cpp which seems to have the correct mapping. So it should not be too complicated to write such a tool after re-engineering the correct offsets etc. HB |

There is a description of the file content here:
https://www.thecalculatorstore.com/c/hp1...ser-memory And there is at least a project of a program to read and write HP15c CE memory files. I am testing a beta build of it! |

Thanks for the info, that means that I don't have to write such a thing myself :-) and can just wait for good things to happen. That said, if more beta testers are needed, I'd be more than happy to help. Cheers HB |

FYI my original 2012 HP "Virtual Calculators" (HP-15C & HP-12C) stored memory in files 2040 bytes in size and not 2048. That is 255x8 and not 256x8. So 8 bytes are not used for whatever reason. However the VoyagerSave ones are 2048 bytes. (09-07-2024 08:45 PM)Divasson Wrote: And there is at least a project of a program to read and write HP15c CE memory files. That's great news. I look forward to trying it. Websites are great when the internet is accessible. Which it always is. Except when it isn't A1 PS: I should note that the HP HP-12C Platinum virtual calculator appears to use the Sunplus SoC emulator under the hood. It saves a 18KB binary file containing who-knows-what. From what I've read the Generalplus and Sunplus SoC's are pretty much the same. Both use a masked-ROM for (fixed) firmware and have no means to read/write RAM.
