The update_all menu won't appear
I seem to be missing some cores on my MiSTerFPGA, such as Tempest. I haven't used the system in about 12 months, so downloaded the latest update_all.sh and put it on the MiSTer and ran it. I wanted to view the update_all options to see if anything is unchecked that would prevent all available cores being installed. The update_all repo instructions say that there should be a countdown that appears when running update_all and to press up on the keyboard during the countdown to access its menu. However, when I run update_all there is no countdown and the script just runs (without errors) but no menu is sown when I hold up on the keyboard at the start. Anyone know what the issue might be here?
