@Beefington Sorry if you thought that, but, you didn't offend me, and I didn't want to look hostile. Please understand that English is not my native language, perhaps my objectivity has made that impression.
I also didn't mean that you are impatient, I just said "please be patient and wait for the next version" because expecting something good always causes anxiety, so it is common to talk to users "be patient".
this topic was different to the one previously raised (which was not 'solved' either)

but cannot scroll the scroll bars in menus to find the disk required
I researched more about it and found the hatari documentation:

If you read until the end, you will notice that in the part that talks about joypad (https://docs.libretro.com/library/hatari/#joypad), it is clear that if you press select you enable "Mouse mode toggle", then, to change the disc, you need to access the menu with "Y", press "select", and use the joystick as if it were a mouse, using button A to "click the mouse".
Please test, check, and give feedback.
