HP41 ROMHandler software published (beta)

Post by MeinKuipers »

Happy to announce the first public BETA version of ROMHandler, a Windows program to manipulate MOD and ROM files for the HP41, i41CX, DM41X and HP41CL. It is based on the MLDL2000 Manager Mk2M, but with all hardware dependecies removed is is now a standalone program.

Its two main features are a MOD file manipulator and a ROM file disassembler. Compared with the most recent version of M2kM it offers the following previously undocumented features:

- disassembly of HEPAX RAM images, recognizes file types
- support for HP41CL commands
- support for HP41CL FLDB image listing
- alert for HP41CL image using upper bits
- lists HP41CL YCRC
- alert for HEPAX RAM file (xFF3 = 200)
- supports lower case mnemonics and mnemonics without spaces (CalypsiNut style)
- HEXdump of a ROM image
- analysis of DM41X RAM file, and splits this file in seperate ROM files
- opens i41CX mailmod files
- listwindow and disassembly lister can have selectable fontsize (with Preferences)

This is beta software for Windows only an not heavily tested. I do not have a manual yet, parts of the M2kM manual apply. Please report any issues.

Software can be dowloaded at https://github.com/mjakuipers/ROMHandler
