During runtime you cannot change the image, more exactly, the emulation will not notice that you changed the image. The reason is that MAME reads the disk image when mounting and converts it internally to a low-level magnetic flux sequence. The flux sequence is converted back to the image format when you leave the emulation. That also means that the image file is not updated until the emulation is closed. This is also true for the hard disk images which are processed in a similar way. In this situation, if you don't want to shut down the emulation, your only chance is to unmount the disk image in the OSD menu. This has the same effect. Then you can change the image and remount it. An exception is TIPI. Here, the TIPI has the files on its own file system, and it exchanges the files with MAME during the file operations. So the files will also be updated on the TIPI on write operations in the emulation. Thanks for the clarification. TIPI looks interesting but necessarily complex. I'll work with manually unmounting/remounting the disk in mame for now. Quote Link to comment Share on other sites More sharing options...
