Heads map modification in ROM dump file (tips)

[Filipp_TS]

Hi everyone!

Sometimes might be necessary to edit Heads map or block SA access.
How to do that just in the ROM dump file using Hex Editor?

Open the ROM dump file you have in Hex editor,

Use a plugins button: in WDC Marvell option use 'ROM map' menu -> 'ROM edit'
Then right mouse click on '0A' ROM module (it is a Heads map) -> "Edit content".
There, use a 'Heads map editor' option in plugins,
modify heads map as you need.
Save this modified 0A module to file.
Then again right mouse click on '0A' module in the list of ROM modules in opened ROM dump -> 'LoadFromFile' option,
select your saved modified 0A module, click OK, save this prepared ROM dump,
then write it on the drive.

The same process you can use with 0B/20B ROM module for SA Regions block purpose.
Use a "ROM Falsh Dir edit" option in Plugins when opened 0B/20B ROM module.
Save modified module to file, then load it into the ROM by the same mthodics like described above.

Then you can write a prepared ROM dump file on the drive.
