Import (Ctrl+I) overlays TXT or XLSX data on the current session.
Choose a file, then an XLSX sheet or named TXT section. A TXT file without sections is imported as a whole. Only RAM cells, registers, and flags present in the selected data are changed; all other values remain intact.
The application asks before importing over unsaved changes. Invalid hexadecimal values, unknown registers, and malformed file structures produce an error.
