I am on Windows 11, and I am looking for a way to extract the OS39RA.A80 file from a ZIP archive consisting of two files OS39RA_1.A80 and OS39RA_2.A80 which are contained in the OS39RA.ZIP archive.
?
I tried with winrar without success. It does not consider it as a multi-file archive.
I also used the unzip program of the iso file, but it does not work because it's a 32bits
