ROM Layout Manager

Deselect if exporting to an EEPROM programmer and later on installed on a real 41 calculator. This option does also affect the ROM’s consolidation (see above). ROM’s are always stored in Genesis-41 emulator as “LittleEndian” format.

Move slider to select Page or “Block”

Load, Export, Detach selected Page. Result is saved into a binary file with .ROM extension

Fill selected Page with writable “memory”

Note: ROM’s files must be loaded into Genesis-41 as exact dumps of the original calculator operating system or third party modules. These files are available on the Internet or can also be created by extracting them from the .MOD files provided here.

Select depending on which CPU architecture the ROM may have to be loaded later on.

This option does also affect the ROM’s consolidation (see above). Consolidating ROM’s into the runtime Resource directory will save them as indicated with this option.

On an Intel machine, ROM’s are always running as “LittleEndian” and this is the case for Genesis-41 running on Intel. However this should not be too much of a concern because this format is invisible to the user and Genesis-41 takes care of the conversion when loading the ROM.

On a PowerPC or a real HP-41 calculator they would need to run as “BigEndian”. To reduce the possible confusion, it is recommended to always store these ROM’s into files as “BigEndian” format.

Simply put, change this option only if you know what you do.

Fill start/end & destination address fields for moving or clearing data across banks within the 64K memory range

Note: ROM files must be loaded into Genesis-41 as exact dumps of the original calculator operating system or third party modules. These files are available on the Internet or can also be created by extracting them from the .MOD files provided here.

Select and Click to load or save a full 4x64K layout configuration (4 banks x 16 pages). A total of 24 configurations are possible

Click to toggle Read/Write selected Page. Used when patching module content

Click to Enable/Disable selected Page. Useful when manipulating modules which might not coexists within the 64K memory space

Indicates Page is currently read by the calculator

Indicates Page is in Read/Write mode

2 slots (upper and lower) loaded with Hepax “memory” must be formatted with HEPINI function

custom module, contains HEPINI ROM formatting tool

Select to copy previously loaded ROM files (from various directories) into the bundle Resource directory. Useful when reloading the configuration, all ROM’s will be automatically inserted into their slot from the consolidated directory.

Select to use this configuration when starting the calculator

Move sliders to select Bank

Indicates that this slot is occupied, inserting an EEPROM will erase the current content
