Add ability to edit a memory mapped file

Post by MegaIng »

It would be helpful to have an option to open a file in memory mapped mode in HxD, even when another process is accessing it simultaneously. Currently, when a file is already open in another program that uses read-write memory mapped mode, it cannot be edited in HxD. However, the other program may only be reading the file, rather than writing to it. Therefore, it would be nice to have an option to allow live editing of the file in HxD, with the understanding that any changes made by the other process would also be visible, and any edits made in HxD could potentially be lost. While data consistency is typically a concern, in this scenario, I would prefer live editing capabilities.

In my specific situation I have a CPU in a logic simulator that reads a Program ROM (microcode) via memory mapping, but the simulator opens the file in read-write since the simulator doesn't know that the specific architecture only reads.
